DESCRIPTION

The VS-20CTQ... center tap Schottky rectifier series has

been optimized for low reverse leakage at high temperature.

The proprietary barrier technology allows for reliable

operation up to 175 °C junction temperature. Typical

applications are in switching power supplies, converters,

freewheeling diodes, and reverse battery protection.
