PD -20358E 22DGQ045 SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 25A, 45V Major Ratings and Characteristics Characteristics 22DGQ045 Units IF(AV) 25 A VRRM (Per Leg) 45 V IFSM @ tp = 8.3ms half-sine (Per Leg) 300 A 0.76 V VF @ 25Apk, TJ =125°C (Per Leg) 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-PRF19500 quality conformance testing is available on source controlled drawings to TX, TXV and S levels.
