Description/ Features
Major Ratings and Characteristics
Characteristics
The 175BGQ030 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 150°C junction temperature. Typical applications are in
switching power supplies, converters, reverse battery protection,
and redundant power subsystems.
