WEBOne other interesting detail is related to SiC's bandgap. The wide bandgap leads to a high forward voltage for SiC diodes, and thus you have to be careful when relying on the body diode in a SiC MOSFET—in the case of the C3M0075120K, the forward voltage drop is around 4 V! However, focusing on the negative is somewhat beside the …
