| PD -94014A SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 35SGQ030 35 Amp, 30V Major Ratings and Characteristics Characteristics IF(AV) VRRM IFSM @ tp = 8.3ms half-sine 300 VF @ 35Apk, TJ =125C 0.69 A V 35SGQ030 Units 35 30 A V Description/Features The 35SGQ030 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 control drawings to TX, TXV and S quality levels.
