ST’s portfolio of silicon-carbide MOSFETs features the industry’s highest operating junction temperature rating of 200 °C and significantly reduced total power losses for more efficient, smaller and lighter systems. 

They feature a very low on-state resistance (RDS(on)) per area even at high temperatures and excellent switching performance versus the best-in-class silicon technologies, with minimal variation versus temperature. Bring all the benefits of silicon-carbide MOSFETs to your system with ST’s SiC MOSFET technology. SiC MOSFETs are belonging to the STPOWER™ family.

New 650 V, 22 mΩ typ (at 150 °C) SiC power MOSFET

ST has extended its portfolio of SiC MOSFETs with the introduction of the 22 mΩ typ (at 150 °C), 650 V SCTW100N65G2AG which increases the electrical efficiency of EVs and hybrid vehicles. When used in the EV/HEV main inverter, it increases the efficiency by up to 3% compared with an equivalent IGBT solution, translating into longer battery life and a lighter power unit. ST’s SiC MOSFETs also feature the industry’s highest junction-temperature rating of 200°C and show a very small variation of the on-state resistance even at high temperatures. This leads to higher system efficiency, which reduces cooling requirements and PCB form factors simplifying thermal management.
The new 650 V SiC MOSFET is currently sampling to lead customers and will soon complete the qualification to AEC-Q101.
