MSE Supplies offers SiC Epitaixal wafer on SiC substrate. They have the advantages of operating under high-voltage, high electric current, and at high temperatures compared to semiconductor devices based on silicon. These unique features of SiC epitaxial wafers lead to the miniaturization of devices, enabling smaller and lighter power control modules to be made. They are often used for power devices (schottky diodes, MOSFETs, JEFTs, BJTs, IGBTs), thyristors for green energy systems (solar inverters), hybridand electric vehicles and numerous other energy-efficient systems.
