Infineon Technologies AG will provide customers with comprehensive Product Carbon Footprint (PCF) data, taking a pioneering role in the semiconductor industry. The company is committed to eventually providing PCF data for its entire product portfolio, starting now with about half of its portfolio.
The initiative will empower customers to advance their own sustainability goals and reduce their carbon footprint effectively along the entire supply chain. The Product Carbon Footprint is a metric that quantifies the greenhouse gas emissions associated with an individual product, allowing the comparison of different products’ climate impact. Infineon will share more insights with customers at the upcoming PCIM trade fair in Nuremberg, Germany, from 11 to 13 June 2024.
“By providing comprehensive Product Carbon Footprint data, we are driving the vision of a net-zero society and empowering our customers to reduce carbon emissions even more effectively,” says Elke Reichart, Member of the Management Board and Chief Digital and Sustainability Officer at Infineon. “Infineon is taking a leading role in carbon transparency by committing to include the entire product portfolio over the coming years. This underlines our ambition to be a leader not only in terms of technology, but also sustainability.”
The specific data Infineon provides on its individual products is essential for the growing number of customers who want to increase transparency on their own carbon footprint. Moreover, it supports informed decision making to leverage additional potential for reducing emissions along the value chain.
In the absence of established industry standards, Infineon has developed a robust methodology to calculate the Product Carbon Footprint, incorporating customer needs and best practices. Infineon includes emissions from raw materials and supplies, its own manufacturing processes, manufacturing partners and transportation to the customer (“from cradle to gate”).
This means that the Product Carbon Footprint reported by Infineon covers scope 1 and 2 emissions as well as scope 3 emissions from suppliers and manufacturing partners, all the way to the customer’s gate. The Product Carbon Footprint is expressed in kilograms of carbon dioxide equivalent (kg CO 2e).
Infineon has published the assessment of reference product families on the Infineon website.
Driving transparency goes hand in hand with Infineon’s strong commitment to decarbonization and digitalization. Infineon’s products make a major contribution to the global energy transition and thus to a net-zero society. They are used in solar and wind power plants, electric cars and increase energy efficiency in numerous applications, including AI data centers. Over their lifetime, the company’s chips overall save 34 times the amount of CO 2e emitted during their production.
Breaking the carbon footprint down to the product level is another major milestone in Infineon’s sustainability journey. Infineon has already pledged to achieve carbon neutrality by 2030 for direct and indirect emissions (scope 1 and 2). Last year, the company additionally committed to setting a science-based target encompassing supply chain emissions (scope 3) as well.

Infineon Technologies AG announced two new CoolGaN™ product technologies, CoolGaN bidirectional switch (BDS) and CoolGaN Smart Sense. CoolGaN BDS provides exceptional soft- and hard-switching behavior, with bidirectional switches available at 40 V, 650 V and 850 V. Target Applications of this family include mobile device USB ports, battery management systems, inverters, and rectifiers.
The CoolGaN Smart Sense products feature lossless current sensing, simplifying design and further reducing power losses, as well as transistor switch functions integrated into one package. They are ideal for usage in consumer USB-C chargers and adapters.
The CoolGaN BDS high voltage will be available at 650 V and 850 V and feature a true normally-off monolithic bi-directional switch with four modes of operation. Based on the gate injection transistor (GIT) technology, the devices have two separate gates with substrate terminal and independent isolated control. They utilize the same drift region to block voltages in both directions with outstanding performance under repetitive short-circuit conditions.
Applications can benefit by using one BDS instead of four conventional transistors, resulting in higher efficiency, density, and reliability. Furthermore, significant cost savings are achieved. The devices optimize performance in the replacement of back-to-back switches in single-phase H4 PFC and HERIC inverters and three-phase Vienna rectifiers. Additional implementations include single-stage AC power conversion in AC/DC or DC/AC topologies.
The CoolGaN BDS 40 V is a normally-off, monolithic bi-directional switch based on Infineon’s in-house Schottky Gate GaN technology. It can block voltages in both directions, and through a single-gate and common-source design, it is optimized to replace back-to-back MOSFETs used as disconnect switches in battery-powered consumer products. The first 40 V CoolGaN BDS product has a 6 mΩ R DS(on), with a range of products to follow. Benefits of using 40 V GaN BDS vs. back-to-back Si FETs include 50 – 75 percent PCB area savings and a reduction of power losses by more than 50 percent, all at a lower cost.
The CoolGaN Smart Sense products feature 2 kV electrostatic discharge withstand and can connect to controller current sense for peak current control and overcurrent protection. The current sense response time is ~200 ns, which is equal or less than common controller blanking time for ultimate compatibility.
Implementing the devices results in increased efficiency and cost savings. At a higher R DSs(on) of e.g. 350 mΩ, the CoolGaN Smart Sense products offer similar efficiency and thermal performance at lower cost compared to traditional 150mΩ GaN transistors. Moreover, the devices are footprint compatible to Infineon’s transistor-only CoolGaN package, eliminating the need for layout rework and PCB respin, and further facilitating design with Infineon’s GaN devices.
Engineering samples of the CoolGaN BDS 40 V are available now for 6 mΩ and will follow in Q3 2024 for 4 mΩ and 9 mΩ. Samples of the CoolGaN BDS 650 V will be available in Q4 2024, and 850 V will follow early 2025. CoolGaN Smart Sense samples will be available in August 2024.

The electronics industry is witnessing a significant shift towards more compact and powerful systems, driven by technological advancements and a growing focus on decarbonization efforts. With the introduction of the Thin-TOLL 8×8 and TOLT packages, Infineon Technologies AG is actively accelerating and supporting these trends. They enable a maximum utilization of the PCB mainboard and daughter cards, while also taking the system’s thermal requirements and space restrictions into account.
The company is now expanding its portfolio of CoolSiC™ MOSFET discretes 650 V with two new product families housed in the Thin-TOLL 8×8 and TOLT packages. They are based on the CoolSiC Generation 2 (G2) technology, offering significantly improved figures-of-merit, reliability, and ease-of-use. Both product families specifically target high and medium switching-mode power supplies (SMPS), including AI servers, renewable energy, EV chargers, and large home appliances.
The Thin-TOLL package has a form factor of 8×8 mm and offers the best-in-class Thermal Cycling on Board (TCoB) capability on the market. The TOLT package is a top-side cooled (TSC) enclosure with a similar form factor to TOLL. Both package types offer developers several benefits: Using them in AI and server power supply units (PSU), for example, reduces the thickness and length of the daughter cards and allows for a flat heat sink.
When used in microinverters, 5G PSU, TV PSU and SMPS, the Thin-TOLL 8×8 package allows for a minimization of the PCB area occupied by the power supply devices on the mainboard, while TOLT keeps the junction temperature of the devices under control, given that these applications typically use convection cooling. In addition, TOLT devices complete Infineon’s top-side cooled CoolSiC industrial portfolio, namely CoolSiC 750 V in Q-DPAK. They enable developers to reduce the PCB footprint occupied by SiC MOSFETs when the power to be delivered to the devices does not require a Q-DPAK package.
The CoolSiC MOSFETs 650 V G2 in ThinTOLL 8×8 and TOLT are now available in R DS(on) from 20, 40, 50 and 60 mΩ. Additionally, the TOLT variant is also available with an R DS(on) of 15 mΩ. The product family will be expanded by a more granular portfolio by the end of 2024. More information is available at www.infineon.com/coolsic-gen2. Infineon will showcase the CoolSiC MOSFET 650 V Generation 2 at the PCIM in Nuremberg.

Infineon Technologies AG is on schedule with the construction of the Smart Power Fab in Dresden and is initiating the final construction phase. During a visit, the Prime Minister of the Free State of Saxony, Michael Kretschmer, officially handed over the last outstanding building permit for the new fab issued by the State Directorate of Saxony.
The excavation of the building pit has now been completed. The shell and building construction are currently progressing on the concrete foundation, which is up to two meters thick. Infineon officially broke ground for the new plant in Dresden in May 2023. Manufacturing is scheduled to start in 2026. The production will focus on semiconductors that promote decarbonization and digitalization.
With a total investment of five billion euros, the company is making a significant contribution to the European Commission goal to increase the EU’s share of global semiconductor production to 20 percent by 2030. The semiconductors manufactured in Dresden will secure future value chains in key European industries. The products manufactured in the new production facility will be used in the automotive and renewable energy industries. The interaction of power semiconductors and analog/mixed-signal components enables particularly energy-efficient and intelligent system solutions – hence the name Smart Power Fab.
“The construction of the Smart Power Fab is a big win for Dresden, Saxony, Germany and Europe,” says Michael Kretschmer, Prime Minister of the Free State of Saxony. “Infineon’s fourth production module in Dresden is another important building block in strengthening Europe’s resilience in the field of microelectronics. It is a further step towards achieving the European Commission’s goal of increasing Europe’s share of global chip production to 20 percent. Thanks to a thoughtful cooperation between the company, the Free State of Saxony, the local authorities, and the federal government, it has been possible to get the investment off the ground and to issue the relevant permits quickly. As a result, the semiconductors that we urgently need for the mobility and energy transition can be produced in the new fab starting in 2026.”
“We are making excellent progress with the construction of our state-of-the-art Smart Power Fab in Dresden. We are right on schedule also thanks to the excellent cooperation with the authorities,” says Dr. Rutger Wijburg, Member of the Management Board and Chief Operations Officer of Infineon. “With our strategic decision to continue investing in Dresden, we are securing the long-term future of the site and strengthening the manufacturing base for semiconductors in Europe.”
The dimensions of the construction site are impressive. On average, construction workers have removed around 8,000 tons of soil every day since the start of work. A total of 450,000 cubic meters of excavated soil has been produced, which corresponds to the volume of 180 Olympic swimming pools.
The soil is being temporarily stored in a specially prepared area near the Dresden Airport freeway junction. The 22-metre-deep pit not only compensates for the natural gradient, but also provides a firm foundation for the 150- to 190-centimetre-thick base plate, which is intended to reduce vibrations – from passing streetcars, for example – to a minimum. Even minimal vibrations can affect the sensitive semiconductor production.
In the next construction phase, the basement levels will be built, along with other levels. The clean room – the heart of the Smart Power Fab – is planned for the fourth level. Once completed, it will be at the exact same height as the site’s three existing production rooms. This will optimize an integrated production. The future construction phase of the project includes a total of ten tower cranes, some of them 80 meters high to support up to 1,200 construction workers who will be working on the site every day in multiple shifts.
The investment in Dresden is part of the company’s strategy to reach CO 2-neutrality by 2030. The Smart Power Fab sets new efficiency standards for the consumption of important resources such as energy and water. This has a positive impact on the carbon footprint of Infineon. Even today, Infineon’s products, which are used in solar and wind power plants, reduce 34 times the amount of CO 2 emitted during their production over their lifetime.
With the investment in the new plant, Infineon is creating an additional 1,000 jobs in the Saxon state capital. The company currently employs approximately 3,250 people in Dresden. The number of trainees has already been significantly increased with the new Fab. Subject to the European Commission’s state aid decision and the national grant procedure, the project is to be funded in accordance with the objectives of the European Chips Act. Infineon is aiming for public funding of around one billion euros.

With the increasing power requirements of Artificial Intelligence (AI) processors, server power supplies (PSUs) must deliver more and more power without exceeding the defined dimensions of the server racks. This is driven by a surge in energy demand of high-level GPUs, which could consume 2 kW and more per chip by the end of the decade.
These needs, as well as the emergence of increasingly demanding applications and the associated specific customer requirements have prompted Infineon Technologies AG to extend the development of SiC MOSFETs to voltages below 650 V. The company is now launching the new CoolSiC™ MOSFET 400 V family, which is based on the second generation (G2) CoolSiC technology introduced earlier this year.
The new MOSFET portfolio was specially developed for use in the AC/DC stage of AI servers, complementing Infineon’s recently announced PSU roadmap. The devices are also ideal for solar and energy storage systems (ESS), inverter motor control, industrial and auxiliary power supplies (SMPS) as well as solid-state circuit breakers for residential buildings.
“Infineon offers an extensive portfolio of high-performance MOSFETs and GaN transistors to meet the demanding design and space requirements of AI server power supplies”, said Richard Kuncic, Head of the Power Systems Business Line at Infineon. “We are committed to supporting our customers with advanced products such as the CoolSiC MOSFETs 400 V G2 to drive highest energy efficiency in advanced AI applications.”
The new family features ultra-low conduction and switching losses when compared to existing 650 V SiC and Si MOSFETs. Implemented in a multi-level PFC, the AC/DC stage of the AI Server PSU can attain a power density of more than 100 W/in³ and is proven to reach 99.5 percent efficiency.
This is an efficiency improvement of 0.3 percentage points over solutions using 650 V SiC MOSFETs. In addition, the system solution for AI Server PSUs is completed by implementing CoolGaN™ transistors in the DC/DC stage. With this combination of high-performance MOSFETs and transistors, the power supply can deliver more than 8 kW with an increase in power density by a factor of more than 3 compared to current solutions.
The new MOSFET portfolio comprises a total of 10 products: five R DS(on) classes from 11 to 45 mΩ in Kelvin-source TOLL and D²PAK-7 packages with .XT package interconnect technology. The drain-source breakdown voltage of 400 V at T vj = 25°C. makes them ideal for use in 2- and 3-level converters and for synchronous rectification.
The components offer high robustness under harsh switching conditions and are 100 percent avalanche tested. The highly robust CoolSiC technology in combination with the .XT interconnect technology enables the devices to cope with power peaks and transients caused by sudden changes in the power requirements of the AI processor. Both the connection technology and a low and positive R DS(on) temperature coefficient enable excellent performance under operating conditions with higher junction temperatures.

The influence of artificial intelligence (AI) is driving up the energy demand of data centers across the globe. This growing demand underscores the need for efficient and reliable energy supply for servers. Infineon Technologies AG opens a new chapter in the energy supply domain for AI systems and unveils a roadmap of energy efficient power supply units (PSU) specifically designed to address the current and future energy need of AI data centers.
By introducing unprecedented PSU performance classes, Infineon enables cloud data center and AI server operators to reduce their energy consumption for system cooling. The innovative PSUs reduce power consumption and CO 2 emissions, resulting in lower lifetime operating costs. The powerful PSUs are not only used in future data centers but can also replace existing power supply units in servers and increase efficiency.
In addition to the current PSUs with an output of 3 kW and 3.3 kW available today, the new 8 kW and 12 kW PSUs will contribute to further increasing energy efficiency in future AI data centers. With the 12 kW reference board, Infineon will offer the world’s first power supply unit that achieves this level of performance and supplies future data centers with power.
“At Infineon, we power AI. We are addressing a critical question of our era – how to efficiently meet the escalating energy demands of data centers,” says Adam White, Division President Power & Sensor Systems at Infineon. “It’s a development that was only possible by Infineon’s expertise in integrating the three semiconductor materials silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) into a single module. Our PSU portfolio is therefore not only an example of Infineon’s innovative strength, which leads to first-class results in terms of performance, efficiency and reliability for data centers and the AI ecosystem. It also reinforces Infineon’s market leadership in power semiconductors.”
Infineon is responding to the requirements of data center operators for higher system efficiency and lower downtimes. The growth of server and data center applications has led to an increase in power requirements, necessitating the development of power supplies with higher power ratings from 800 W up to 5.5 kW and beyond. This increase is driven by the growing power requirements of Graphic Process Units (GPU) on which AI applications are computed.
High-level GPUs now require up to 1 kW per chip reaching 2 kW and beyond by the end of the decade. This will lead to higher overall energy demand for data centers. Depending on the scenario, data centers will account for up to seven percent of global electricity consumption by 2030; this is an order of magnitude comparable to India’s current electricity consumption.
Infineon’s new PSUs contribute to the efforts to limit the CO 2 footprint of AI data centers despite the rapidly growing energy requirements. This is made possible by a particularly high level of efficiency that minimizes power losses. Infineon’s new generation PSUs achieve an efficiency of 97.5 percent and meet the most stringent performance requirements. The new 8 kW PSU is capable of supporting AI racks with an output of up to 300 kW and more. Efficiency and power density is increased to 100 watts per in³ compared to 32 W/in³ in the available 3 kW PSU, providing further benefits for the system size and cost savings for operators.
From a technical perspective, this is made possible by the unique combination of the three semiconductor materials Si, SiC and GaN. These technologies contribute to the sustainability and reliability of AI server and data center systems. Innovative semiconductors based on wide-bandgap materials such as SiC and GaN are the key to a conscious and efficient use of energy to drive decarbonization.
The 8 kW Power Supply Unit will be available in Q1 2025. For more information about the PSU roadmap, please click here.
