SCHOTTKYRECTIFIER

HIGH EFFICIENCY SERIES

22DGQ045

25A, 45V

MajorRatingsandCharacteristics

Description/Features

The 22DGQ045 (series doubler) Schottky rectifier has

been expressly designed to meet the rigorous

requirements of hi-rel environments. It is packaged in the

hermetic isolated TO-254AA package. The device's

forward voltage drop and reverse leakage current are

optimized for the lowest power loss and the highest circuit

efficiency for typical high frequency switching power

supplies and resonent power converters. Full MIL-PRF-

19500 quality conformance testing is available on source

controlled drawings to TX, TXV and S levels.
