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.
