WebOct 14, 2024 · These details may include the maximum current, voltage rating and R DS(on) values (for MOSFETs), and charge (for SiC diodes). Other details that are good to know right after are the package type and a quick glance at the features in case the application requires specific things like fast switching speed and low reverse recovery (Q RR ). WebMar 28, 2024 · 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.
