STPS20SM100ST

STPS20SM100ST Description

The STPS20SM100ST from STMicroelectronics is a high-performance Schottky diode designed for fast recovery and high-efficiency rectification in power applications. With a 100V reverse voltage (Vr) and 20A average forward current (Io), it delivers robust performance in demanding environments. Its low forward voltage drop (900mV @ 20A) minimizes power losses, while the fast recovery time (<500ns) ensures efficient switching in high-frequency circuits. Packaged in a TO-220 through-hole format, this diode is ideal for heat dissipation and easy integration into power supplies, inverters, and motor drives.
