Silicon Carbide SiCSTMicroelectronics
Silicon Carbide (SiC) is a wide bandgap material. Wide bandgap technologies have many advantages compared to Silicon. Operating temperatures are higher heat dissipation is improved and switching and conduction losses are lower. However wide bandgap materials are more difficult to mass produce compared to silicon based ones.
