DESCRIPTION
VF at IF
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.
