The Ins And Outs Of Silicon Carbide

19.03.2020· Fig. 1: SiC MOSFET. Source: Cree. SE: How about with SiC? Palmour: Silicon carbide has a 10 times higher breakdown field.Our 600-volt MOSFET is going to be as fast as a 60-volt silicon MOSFET. The other way to look at it is if you say 600 volts is the voltage at which you switch from MOSFETs and silicon over to IGBTs, we would be at 10 times higher voltage.
