WNSCx 650V Silicon Carbide (SiC) Diodes WeEn Semiconductors WNSCx 650V Silicon Carbide (SiC) Diodes are designed for high-frequency switched-mode power supplies with highly stable switching performance. These diodes feature high forward surge capability IFSM, fast reverse recovery time, high-efficiency, reduced losses in associated MOSFET, and reduced Electro-Magnetic Induction (EMI). The WNSCx SiC diodes offer high-power density and come in a DFN 8mm x 8mm plastic package. Typical applications include UPS, photovoltaic (PV) inverter, telecom SMPS, server SMPS, LED / OLED TV, PC silver box, power factor correction, and motor drives.
