Silicon carbide - The latest breakthrough in high-voltage switching and rectification

ST’s portfolio of silicon carbide (SiC) devices incluses STPOWER SiC MOSFETs ranging from 650 to 2200 V with the industry’s highest junction temperature rating of 200 °C for more efficient and simplified designs, and STPOWER SiC diodes ranging from 600 to 1200 V which feature negligible switching losses and 15% lower forward voltage (VF) than standard silicon diodes. Check our Innovation and Technology page about SiC
