( Typical)
The Schottky rectifier module has been optimized for ultra
low forward voltage drop specifically for the OR-ing of parallel
power supplies. The proprietary barrier technology allows for
reliable operation up to 125 °C junction temperature. Typical
applications are in parallel switching power supplies, converters, reverse battery protection, and redundant power
subsystems.
