Among SiC MOSFET structures, the trench MOSFET has a low channel resistance thanks to its high channel density and mobility[5, 6]. However, in a high-voltage SiC MOSFET (a voltage of 3.3 kV or above), the channel resistance does not have a significant effect because of the high drift resistance. In addition, at high voltages, the trench MOSFET ...

One 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 point here.
