SemiQ Inc has announced a family of co-packaged 1200 V SOT-227 MOSFET modules based on its third-generation SiC technology.
In addition to smaller die sizes, third generation SIC devices offer faster switching speeds and reduced losses.
The family of highly rugged and easy mount devices currently offers six devices with an RDSon range of 8.4 to 39 mΩ: GCMS008C120S1-E1, GCMX008C120S1-E1, GCMS016C120S1-E1, GCMX016C120S1-E1, GCMS040C120S1-E1 and GCMX040C120S1-E1, with the GCMX040C120S1-E1 having a switching time as low as 67 ns. In addition to these six, two further modules – GCMS080C120S1-E1 and GCMX080C120S1-E1 – are available, each with an RDSon of 80 mΩ.
The COPACK MOSFETs with Schottky barrier diode provides exceptional switching losses at high junction temperature due to the low turn on switching losses.
SemiQ is targeting the robust SiC MOSFET modules at applications including solar inverters, energy storage systems, battery charging, and server power supplies. All devices have been screened with wafer-level gate-oxide burn-in tests and tested beyond 1400 V, with avalanche testing to 330 mJ (RDSon = 39 mΩ) or 800 mJ (RDSon = 16.5 or 8.4 mΩ).
In addition to having a drain-to-source voltage (VDS) of 1200 V, the MOSFET reduces total switching losses to as low as 468 µJ and a reverse recovery charge of 172 nC (GCMX040C120S1-E1). The family also has a low junction-to-case thermal resistance and comes with an isolated backplate and the ability to directly mount to a heatsink by 4kVAC galvanic isolation testing.
Specifications: Ratings and electrical/thermal characteristics
The QSiC 1200 V MOSFET modules have a continuous operational and storage temperature of -55oC to 175oC. It has a recommended operational gate-source voltage of -4.5/18 V, with a VGSmax of -8/22 V, and a power dissipation of 183 to 536 W (RDSon = 39 and mΩ, core and junction temperature 25oC).
For static electrical characteristics, the device has a junction-to-case thermal resistance of 0.23oC per watt (RDSon = 8.4) as well as a typical zero-gate voltage drain current of 100 nA, and a gate-source voltage current of 10 nA.
The fastest switching device has a turn-on delay time of 13 ns with a rise time of 7 ns; its turn-off delay time is 18 ns with a fall time of 29 ns.

The market for electric vehicles continues to gather pace with a strong volume growth of both battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). The share of electric vehicles produced is expected to see double-digit growth by 2030 with a share of around 45 percent compared to 20 percent in 2024. Infineon Technologies AG is responding to the growing demand for high-voltage automotive IGBT chips by launching a new generation of products. Among these offerings are the EDT3 (Electric Drive Train, 3 rd generation) chips, designed for 400 V and 800 V systems, and the RC-IGBT chips, tailored specifically for 800 V systems. These devices enhance the performance of electric drivetrain systems, making them particularly suitable for automotive applications.
The EDT3 and RC-IGBT bare dies have been engineered to deliver high-quality and reliable performance, empowering customers to create custom power modules. The new generation EDT3 represents a significant advancement over the EDT2, achieving up to 20 percent lower total losses at high loads while maintaining efficiency at low loads. This achievement is due to optimizations that minimize chip losses and increase the maximum junction temperature, balancing high-load performance and low-load efficiency. As a result, electric vehicles using EDT3 chips achieve an extended range and reduce energy consumption, providing a more sustainable and cost-effective driving experience.
“Infineon, as a leading provider of IGBT technology, is committed to delivering outstanding performance and reliability”, says Robert Hermann, Vice President for Automotive High Voltage Chips and Discretes at Infineon Technologies. “Leveraging our steadfast dedication to innovation and decarbonization, our EDT3 solution enables our customers to attain ideal results in their applications.”
The EDT3 chipsets, which are available in 750 V and 1200 V classes, deliver high output current, making them well-suited for main inverter applications in a diverse range of electric vehicles, including battery electric vehicles, plug-in hybrid electric vehicles, and range-extended electric vehicles (REEVs). Their reduced chip size and optimized design facilitate the creation of smaller modules, consequently leading to lower overall system costs. Moreover, with a maximum virtual junction temperature of 185°C and a maximum collector-emitter voltage rating of up to 750 V and 1200 V, these devices are well-suited for high-performance applications, enabling automakers to design more efficient and reliable powertrains that can help extend driving range and reduce emissions.
“Infineon, as Leadrive’s primary IGBT chip supplier and partner, consistently provides us with innovative solutions that deliver system-level benefits,” said Dr. Ing. Jie Shen, Founder and General Manager of Leadrive. “The latest EDT3 chips have optimized losses and loss distribution, support higher operating temperatures, and offer multiple metallization options. These features not only reduce the silicon area per ampere, but also accelerate the adoption of advanced packaging technologies.”
The 1200 V RC-IGBT elevates performance by integrating IGBT and diode functions on a single die, delivering an even higher current density compared to separate IGBT and diode chipset solutions. This advancement translates into a system cost benefit, attributed to the increased current density, scalable chip size, and reduced assembly effort.
Infineon’s latest EDT3 IGBT chip technology is now integrated into the HybridPACK™ Drive G2 automotive power module, delivering enhanced performance and capabilities across the module portfolio. This module offers a power range of up to 250 kW within the 750 V and 1200 V classes, enhanced ease of use, and new features such as an integration option for next-generation phase current sensors and on-chip temperature sensing, contributing to system cost improvements.
All chip devices are offered with customized chip layouts, including on-chip temperature and current sensors. Additionally, metallization options for sintering, soldering and bonding are available on request.
