ROHM has developed automotive-grade AEC-Q101 qualified 4th Generation 1200V IGBTs that combine class-leading low loss characteristics with high short-circuit resistance. This makes the devices ideal for vehicle electric compressors and HV heaters as well as industrial inverters.
The current lineup includes RGA80TRX2HR / RGA80TRX2EHR / RGA80TSX2HR / RGA80TSX2EHR – in two discrete package types (TO-247-4L and TO-247N), along with 11 bare chip variants – SG84xxWN – with plans to further expand the lineup in the future.
The increasing use of higher voltages in automotive systems and industrial equipment has led to a growing demand for power devices capable of handling high voltages in applications such as vehicle electric compressors, HV heaters, and inverters for industrial equipment.
At the same time, there is a strong push for high efficiency power devices to improve energy conservation, simplified cooling mechanisms, and smaller form factors for a decarbonized society. Automotive electrical components must also comply with automotive reliability standards, while power devices for inverter and heater circuits are required to provide current interruption capabilities during short circuits, necessitating high short-circuit tolerance.
In response, ROHM redesigned the device structure and adopted an appropriate package to develop new 4th Generation IGBTs suitable for high voltage by delivering industry-low loss characteristics with superior short-circuit tolerance.
These devices achieve an industry-leading short-circuit withstand time of 10µs (Tj=25°C) together with low switching and conduction losses while maintaining a high withstand voltage of 1200V and meeting automotive standards by reviewing the device structure, including the peripheral design. At the same time, the new TO-247-4L package products, which feature 4 terminals, can accommodate an effective voltage of 1100V in a ‘Pollution Degree 2 environment’ by ensuring adequate creepage distance between pins. This enables support for higher voltage applications than conventional products.
Implementing creepage distance measures on the device side alleviates the design burden for manufacturers. On top, the TO-247-4L package achieves high-speed switching by including a Kelvin emitter terminal, resulting in even lower losses. In fact, when comparing the efficiency of the new TO-247-4L packages with conventional and standard products in a 3-phase inverter, loss is reduced by about 24% compared to standard products and by 35% over conventional products – contributing to higher efficiency in drive applications.
ROHM will continue to expand its lineup of high-performance IGBTs that contribute to greater miniaturization and high efficiency drive in automotive and industrial equipment applications.

After announcing the world’s first 300-millimeter gallium nitride (GaN) power wafer and opening the world’s largest 200-millimeter silicon carbide (SiC) power fab in Kulim, Malaysia, Infineon Technologies AG has unveiled the next milestone in semiconductor manufacturing technology.
Infineon has reached a breakthrough in handling and processing the thinnest silicon power wafers ever manufactured, with a thickness of only 20 micrometers and a diameter of 300 millimeters, in a high-scale semiconductor fab. The ultra-thin silicon wafers are only a quarter as thick as a human hair and half as thick as current state-of-the-art wafers of 40-60 micrometers.
“The world’s thinnest silicon wafer is proof of our dedication to deliver outstanding customer value by pushing the technical boundaries of power semiconductor technology,” said Jochen Hanebeck, CEO at Infineon Technologies. “Infineon’s breakthrough in ultra-thin wafer technology marks a significant step forward in energy-efficient power solutions and helps us leverage the full potential of the global trends decarbonization and digitalization. With this technological masterpiece, we are solidifying our position as the industry’s innovation leader by mastering all three relevant semiconductor materials: Si, SiC and GaN.”
This innovation will significantly help increase energy efficiency, power density and reliability in power conversion solutions for applications in AI data centers as well as consumer, motor control and computing applications. Halving the thickness of a wafer reduces the wafer’s substrate resistance by 50 percent, reducing power loss by more than 15 percent in power systems, compared to solutions based on conventional silicon wafers.
For high-end AI server applications, where growing energy demand is driven by higher current levels, this is particularly important in power conversion: Here voltages have to be reduced from 230 V to a processor voltage below 1.8 V. The ultra-thin wafer technology boosts the vertical power delivery design, which is based on vertical Trench MOSFET technology and allows a very close connection to the AI chip processor, thus reducing power loss and enhancing overall efficiency.
“The new ultra-thin wafer technology drives our ambition to power different AI server configurations from grid to core in the most energy efficient way,” said Adam White, Division President Power & Sensor Systems at Infineon. “As energy demand for AI data centers is rising significantly, energy efficiency gains more and more importance. For Infineon, this is a fast-growing business opportunity. With mid-double-digit growth rates, we expect our AI business to reach one billion euros within the next two years.”
To overcome the technical hurdles in reducing wafer thickness to the order of 20 micrometers, Infineon engineers had to establish an innovative and unique wafer grinding approach, since the metal stack that holds the chip on the wafer is thicker than 20 micrometers. This significantly influences handling and processing the backside of the thin wafer.
Additionally, technical and production-related challenges like wafer bow and wafer separation have a major impact on the backend assembly processes ensuring the stability and first-class robustness of the wafers. The 20-micrometer thin wafer process builds on Infineon’s existing manufacturing expertise and ensures that the new technology can be seamlessly integrated into existing high-volume Si production lines without incurring additional manufacturing complexity, thus guaranteeing the highest possible yield and supply security.
The technology has been qualified and applied in Infineon’s Integrated Smart Power Stages (DC-DC converter) which have already been delivered to first customers. It underlines the company’s innovation leadership in semiconductor manufacturing as the holder of a strong patent portfolio related to the 20-micrometer wafer technology.
With the current ramp up of the ultra-thin wafer technology Infineon expects a replacement of the existing conventional wafer technology for low voltage power converters within the next three to four years. This breakthrough is bolstering Infineon’s unique position in the market with the broadest product and technology portfolio including silicon, silicon carbide and gallium nitride-based devices which are key enablers of decarbonization and digitalization.
Infineon will present the first ultra-thin silicon wafer publicly at electronica 2024 from 12 to 15 November in Munich (Hall C3, Stand 502).

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).
