DESCRIPTION
The VS-20CTQ...HN3 Series 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.
