DESCRIPTION

The VS-18TQ... 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.
