SCHOTTKY RECTIFIER 40 Amp
Major Ratings and Characteristics Description/Features
This centertap Schottky rectifier has been optimized for ultra
Characteristics Values Units low forward voltage drop specifically for 3.3V output power
supplies. The proprietary barriertechnology allows for reliable
operation up to 150 I junction temperature. Typical
|F(AV) Rectangular 40 A applications are in parallel switching power supplies,
waveform converters, reverse battery protection, and redundant power
subsystems.
