Rise in switching frequency will also be accomplished by SiC transistors as compared to silicon transistors. This is often however another reason that SiC semiconductors could be used to construct significantly smaller-sized components. For off state stress protection by deep p-locations is adopted, for on-state a thick oxide is used https://www.quora.com/profile/Trevor-Flatcher-2/Role-of-Silicon-Carbide-in-Fuel-Cells-Silicon-carbide-SiC-plays-a-crucial-role-in-advancing-fuel-cell-technology-off
