PD -94275B 35SCGQ060 SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 35 Amp, 60V Major Ratings and Characteristics Characteristics Description/Features The 35SCGQ060 center tap Schottky rectifier has been expressly designed to meet the rigorous requirements of hirel 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. 35SCGQ060 Units IF(AV) 35 A VRRM (Per Leg) 60 V IFSM @ tp = 8.3ms half-sine (Per Leg) 400 A VF @ 17.5Apk, TJ =125°C (Per Leg) 0.61 V TJ, Tstg Operating and storage -55 to 150 CASE STYLE • • • • • Hermetically Sealed Center Tap Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability • Lightweight °C 0.12 [.005] 6.60 [.260] 6.32 [.249] 13.84 [.545] 13.59 [.535] 3.78 [.149] 3.53 [.139] 1.27 [.050] 1.02 [.040] A 20.32 [.800] 20.07 [.790] 17.40 [.685] 16.89 [.665] 1 C 2 3 17.40 [.685] 16.89 [.665] 3X 3.81 [.150] 2X B 13.84 [.545] 13.59 [.535] 0.84 [.033] MAX. 1.14 [.045] 0.89 [.035] 0.36 [.014] 3.81 [.150] B A NOT ES: 1. 2. 3. 4.
