DESCRIPTION
The VS-201CNQ050PbF center tap Schottky rectifier
module 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 high current switching power
supplies, converters, freewheeling diodes, welding, and
reverse battery protection.
