Common Silicon Carbide Devices . The most common and popular SiC devices are SiC Schottky Diode Discretes and SiC MOSFETs The SBD structure is advantageous because it eliminates reverse recovery charge. Compared with Si SBDs, SiC SBDs offer lower forward voltage drop and lower on-resistance, which directly improve system efficiency in many converter/inverter appliions.
