Characteristics
100BGQ045
Units
The NEW 100BGQ045 Schottky rectifier has been optimized for
ultra low forward voltage drop specifically for low voltage output in
high current AC/DC power supplies.
The proprietary barrier technology allows for reliable operation up
to 150C junction temperature. Typical applications are in
switching power supplies, converters, reverse battery protection,
and redundant power subsystems.
