STPSC20H12D

STPSC20H12D Description

The STPSC20H12D from STMicroelectronics is a high-performance Silicon Carbide (SiC) Schottky diode designed for demanding power electronics applications. With a 1200V reverse voltage (Vr) and 20A average rectified current (Io), this diode delivers superior efficiency and reliability in high-voltage circuits. Its zero reverse recovery time (trr) and low forward voltage drop (1.5V @ 20A) minimize switching losses, making it ideal for high-frequency operations. The 1650pF junction capacitance @ 0V ensures minimal parasitic effects, enhancing performance in fast-switching environments. Packaged in a TO-220AC through-hole format, it is RoHS3 compliant and suitable for industrial applications.
