DESCRIPTION
The VS-15CTQ... center tap 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.
