PD - 93981A 16SYQ045C SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 16A, 45V Major Ratings and Characteristics Characteristics Description/Features 16SYQ045C Units IF(AV) 16 A VRRM 45 V IFSM @ tp = 8.3ms half-sine 250 A VF @ 16Apk, TJ =125°C 0.85 V TJ,Tstg Operating and storage -55 to 150 °C The 16SYQ045C Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermetic isolated TO-257AA ceramic 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 powerconverters.FullMIL-PRF-19500 quality conformance testing is available on source control drawings to TX, TXV and S levels. • • • • • Hermetically Sealed Ceramic Eyelets Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability • Lightweight 0.13 [.005] A CASE STYLE 10.66 [.420] 10.42 [.410] 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.
