PD-93980A 16SCYQ045C SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 16 Amp, 45V Major Ratings and Characteristics Characteristics Description/Features The 16SCYQ045C center tap Schottky rectifier has been expressly designed to meet the rigorous requirements of hirel 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 quality levels. 16SCYQ045C Units IF(AV) 16 A VRRM (Per Leg) 45 V IFSM @ tp = 8.3ms half-sine (Per Leg) 150 A 0.62 V VF @ 16Apk, TJ =125°C (Per Leg) TJ, Tstg Operating and storage -55 to 150 • • • • • Hermetically Sealed Ceramic Eyelets Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability • Lightweight °C 0.13 [.005] A 10.66 [.420] 10.42 [.410] CASE STYLE 3X Ø 3.81 [.150] 3.56 [.140] 5.08 [.200] 4.83 [.190] 16.89 [.665] 16.39 [.645] 13.63 [.537] 13.39 [.527] 10.92 [.430] 10.42 [.410] 1 2 1.14 [.045] 0.89 [.035] B 3 0.71 [.028] MAX.
