Infineon Technologies CoolSiC™ Automotive 750V G2 MOSFETs

Infineon Technologies CoolSiC™ Automotive 750V G2 MOSFETs are engineered to meet the stringent demands of electric vehicle (EV) applications such as traction inverters, onboard chargers (OBC), and high-voltage DC/DC converters. These silicon carbide (SiC) MOSFETs deliver exceptional efficiency, power density, and thermal performance, enabling next-generation e-mobility systems. With a voltage rating of 750V and second-generation CoolSiC™ technology, these devices offer improved switching behavior and reduced losses compared to traditional silicon solutions. The portfolio includes a range of RDS(on) values from 9mΩ to 78mΩ, providing flexibility for designers to optimize conduction and switching performance.

Available in robust automotive-qualified Q‑DPAK and PG‑TO263‑7 packages, these MOSFETs are AEC-Q101 compliant and support operation up to +175°C. Fast switching capability, low reverse recovery, and short-circuit withstand features ensure high efficiency and reliability in harsh automotive environments. By reducing cooling requirements and enabling compact system designs, CoolSiC™ MOSFETs help increase driving range and support scalable solutions for different power levels in traction and auxiliary systems.
