DESCRIPTION
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.
