PD -20354D SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 25GQ045 35A, 45V Major Ratings and Characteristics Characteristics IF(AV) VRRM IFSM @ tp = 8.3ms half-sine 400 VF @ 35Apk, TJ =125°C 0.84 A V 25GQ045 35 45 Units A V Description/Features The 25GQ045 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 controlled drawings to TX, TXV and S levels. • • • • Hermetically Sealed Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long Term Reliability • Electrically Isolated TJ, Tstg Operating and storage -55 to 150 °C 0.12 [.005] 3.78 [.149] 3.53 [.139] A 13.84 [.545] 13.59 [.535] 6.60 [.260] 6.32 [.249] 1.27 [.050] 1.02 [.040] CASE STYLE 17.40 [.685] 16.89 [.665] 1 2 3 20.32 [.800] 20.07 [.790] 13.84 [.545] 13.59 [.535] B C 17.40 [.685] 16.89 [.665] 0.84 [.033] MAX. 3X 3.81 [.150] 2X 1.14 [.045] 0.89 [.035] 0.36 [.014] BA 3.81 [.150] (ISOLATED BASE) NOTES : 1. 2. 3. 4.
