Description/Features
The center tap Schottky rectifier module has been optimized
for ultra low forward voltage drop specifically for 3.3V output
power supplies. The proprietary barrier technology allows for
reliable operation up to 150 °C junction temperature. Typical
applications are in parallel switching power supplies,
converters, reverse battery protection, and redundant power
subsystems.
