DESCRIPTION

The VS-20TQ... Schottky rectifier series has been optimized

for very low forward voltage drop, with moderate leakage.

The proprietary barrier technology allows for reliable

operation up to 150 °C junction temperature. Typical

applications are in switching power supplies, converters,

freewheeling diodes, and reverse battery protection.
