| PD -93963A SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 35SGQ045 35 Amp, 45V Major Ratings and Characteristics Characteristics IF(AV) VRRM IFSM @ tp = 8.3ms half-sine VF @ 35Apk, TJ =125C 35SGQ045 Units 35 45 300 A V A Description/Features 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 0.79 V TJ,Tstg Operating and storage -55 to 150 C A CASE STYLE C 1 2 3 13.84 [.545] 13.59 [.535] 6.60 [.260] 6.32 [.249] 13.84 [.545] 13.59 [.535] B 17.40 [.685] 16.89 [.665] 0.13 [.005] 3X 3.81 [.150] 2X 1.14 [.045] 0.89 [.035] 0.36 [.014] BA 3.81 [.150] NOTES: 1. 2. 3. 4.
