PD -93963A 35SGQ045 SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 35 Amp, 45V Major Ratings and Characteristics Characteristics Description/Features 35SGQ045 Units IF(AV) 35 A VRRM 45 V IFSM @ tp = 8.3ms half-sine 300 A VF @ 35Apk, TJ =125°C 0.79 V TJ,Tstg Operating and storage -55 to 150 The 35SGQ045 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. • • • • Hermetically Sealed Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability • Lightweight °C 13.84 [.545] 13.59 [.535] A CASE STYLE 6.60 [.260] 6.32 [.249] 13.84 [.545] 13.59 [.535] C 1 2 B 3 0.13 [.005] 17.40 [.685] 16.89 [.665] 3X 3.81 [.150] 2X 1.14 [.045] 0.89 [.035] 0.36 [.014] 3.81 [.150] B A NOTES: 1. 2. 3. 4.
