PD - 93949A SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 30SLJQ045 30 Amp, 45V Major Ratings and Characteristics Description/Features The 30SLJQ045 Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermetic surface mount SMD-0.5 ceramic 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.
