Affordability combined with high performance and efficiency is the key to making electric mobility accessible to a broader market. That’s why Infineon Technologies AG is introducing the HybridPACK™ Drive G2 Fusion, establishing a new power module standard for traction inverters in the e-mobility sector.
The HybridPACK Drive G2 Fusion is the first plug’n’play power module that implements a combination of Infineon’s silicon and silicon carbide (SiC) technologies. This cutting-edge solution provides an ideal balance between performance and cost efficiency, giving more choice in the optimization of inverters.
One of the main differences between silicon and SiC in power modules is that SiC has a higher thermal conductivity, breakdown voltage and switching speed, making it more efficient, but also more expensive than silicon-based power modules. With the new module, the SiC content per vehicle can be reduced, while maintaining vehicle performance and efficiency at a lower system cost. For example, system suppliers can realize nearly the system efficiency of a full SiC solution with only 30 percent SiC and 70 percent silicon area.
“Our new HybridPACK Drive G2 Fusion module underlines Infineon’s innovation leadership in the automotive semiconductor industry,” said Negar Soufi-Amlashi, Senior Vice President & General Manager High Voltage at Infineon’s Automotive division. “Addressing the demand for greater e-mobility range, this technological breakthrough smartly combines silicon carbide and silicon. Integrated in a well-introduced module package footprint it offers compelling cost-performance ratio over pure silicon carbide modules without adding system complexity for automotive system suppliers and vehicle manufacturers.”
HybridPACK Drive G2 Fusion expands Infineon’s HybridPACK Drive power module portfolio and can be quickly and easily integrated in vehicle components or modules without requiring complex adjustments or configurations. The HybridPACK Drive G2 Fusion module features up to 220 kW in the 750 V class. It ensures high reliability over the entire temperature range from -40 °C to +175 °C and improved thermal conductivity.
The unique properties of Infineon’s CoolSiC™ technology and its silicon IGBT EDT3 technology with very fast turn-on enable the use of a single gate driver or dual gate drivers. This allows easy re-design from full silicon or full SiC based inverters to a fusion inverter. Generally, Infineon’s holistic expertise in SiC MOSFET and silicon IGBT technology, power module packaging, gate drivers as well as sensors enables premium products with cost savings at system level. One example is the integration of Swoboda or XENSIV™ Hall sensors in the HybridPACK Drive package for more precise and efficient motor control.
Infineon will showcase the new HybridPACK Drive G2 Fusion at electronica 2024 in Munich from November 12 to 15 (hall C3, booth 502).

Infineon Technologies AG is intensifying its collaboration with suppliers to further reduce CO 2 emissions along the whole supply chain. Infineon hosted its first ever Supplier Sustainability Summit to further stimulate collaboration and incentivize and support suppliers to accelerate their decarbonization journeys. The virtual event brought together about 100 top semiconductor industry suppliers.
“In order to meet our ambitious targets, we need you, our suppliers,” said Elke Reichart, Member of the Board and Chief Digital and Sustainability Officer at Infineon, during her welcome message. “Infineon’s scope 3 emissions make up the lion’s share of our footprint, especially the materials we source from our suppliers. Therefore, we very much look forward to joining forces with you. Together, we can stimulate and implement decarbonization strategies even better.”
Collaboration with suppliers is a fundamental part of Infineon’s overall sustainability strategy. The company has already made significant progress on its way to reaching climate neutrality by 2030; since 2019 Infineon has halved its CO 2 emissions (scope 1 and 2) while doubling revenue at the same time. In December 2023, Infineon added a commitment to setting a science-based target that includes the supply chain (scope 3). The procurement team is actively working with over 100 suppliers, engaging them to define their own science-based targets and implement appropriate reduction measures.
The Supplier Sustainability Summit was an excellent opportunity for Infineon to share learnings from its own climate strategy and journey and to facilitate exchange of best practices among suppliers. For instance, experts from the Infineon electricity procurement team gave insights from their hands-on experience in achieving 100 percent renewable electricity by 2025; whereas two suppliers shared their expertise in effectively setting science-based targets. The topic was deepened in a panel discussion with Infineon leaders and an expert from the CDP (formerly the Carbon Disclosure Project) that offered further practical advice to attendees.
Infineon’s Green Award recognizes and honors suppliers who demonstrated outstanding environmental commitment and advancements throughout the past year. The “Best Performance Award” went to Applied Materials Inc. for its ambitious climate strategy, including a 1.5°C science-based target and the company’s innovative “Xchange” program. As part of the program Infineon is directly collaborating with Applied Materials to increase resource efficiency and reduce emissions. The program enables take-back and refurbishment of spare parts for complex semiconductor equipment, thereby building on the circular economy to create environmental and business benefits for both parties.
The “Best Improvement Award” winner is Sumco Corporation, that has made remarkable progress in environmental sustainability throughout the past year. The Japan-based company is the first silicon wafer supplier to make a public commitment to setting a science-based target. Following discussions at the top leadership level, Sumco acted at an impressive speed, accelerating existing carbon reduction targets and expanding renewable electricity sourcing.
In the category of companies with less than one billion euros revenue, the “Best Improvement Award” went to iwis SE & Co. KG. The Munich-based, family-owned company serves as a great example to many with its ambitious “Zero Carbon 2040 program” and science-based target commitment. Infineon recognizes the proactive approach towards improving the environmental impact of operations and supply chain and the integration of climate targets in the environmental management system at the sites.
“We would like to applaud the winners of our Green Awards: Applied Materials, Sumco and iwis for stepping up and taking responsibility for environmental sustainability and performance,” said Angelique van der Burg, Chief Procurement Officer at Infineon and host of the day. “We believe that this performance will motivate our whole supplier base to raise the bar higher and follow their example. Now let’s make the best practice a standard practice.”
