DESCRIPTION
The VS-40CPQ... center tap Schottky rectifier 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.
