DESCRIPTION
The VS-95SQ015... axial leaded Schottky rectifier has been
optimized for ultralow forward voltage drop specifically for
the OR-ing of parallel power supplies. The proprietary
barrier technology allows for reliable operation up to 100 °C
junction temperature. Typical applications are in parallel
switching power supplies, converters, reverse battery
protection, and redundant power subsystems.
