Silicon Carbide (SiC) Power Devices ROHM Semiconductor SiC Power Devices deliver 10x the dielectric breakdown field strength, 3x the bandgap, and 3x the thermal conductivity of conventional silicon solutions. This translates to lower switching loss, lower ON resistance, and support for high-temperature operation, making it possible to minimize power loss along with module size. ROHM SiC Power Devices also allow designers to use fewer components, further reducing design complexity.
