STPS20S100C

100 V, 20 A power Schottky rectifier

Features

■ High junction temperature capability for

converters located in confined enrironment

■ Low leakage current at high temperature

■ Low static and dynamic losses as a result of the

Schottky barrier

■ Avalanche specification

Description

Schottky barrier rectifier designed for high
