Characteristics
100BGQ015
Units
The 100BGQ015 Schottky rectifier 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.
