PD -94088 10YQ045C SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 10 Amp, 45V Major Ratings and Characteristics Characteristics Description/Features 10YQ045C Units IF(AV) 10 A VRRM 45 V 110 A 0.70 V IFSM @ tp = 8.3ms half-sine VF @ 10Apk, TJ =125°C The 10YQ045C Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermetic isolated TO-257AA 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 levels.
