| PD -20355C SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 45CKQ100 45A*, 100V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM (Per Leg) IFSM @ tp = 8.3ms half-sine (Per Leg) VF @ 25Apk, TJ =125C (Per Leg) 45CKQ100 Units 45* 100 400 0.74 A V A V C Description/Features The 45CKQ100 center tap Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermetic isolated TO-258AA 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 Center Tap 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 *IF(AV) current is limited by pin diameter A 4.19 [.165] 3.93 [.155] 17.65 [.695] 17.39 [.685] 6.85 [.270] 6.09 [.240] 0.12 [.005] 1.14 [.045] 0.88 [.035] CASE STYLE 17.95 [.707] 17.70 [.697] 37.00 [1.457] 20.40 [1.197] 19.05 [.750] 12.70 [.500] 1 2 3 21.20 [.835] 20.70 [.815] 13.97 [.550] 13.46 [.530] C B 5.08 [.200] 2X 3X 1.65 [.065] 1.39 [.055] CA C B 3.55 [.140] 0.50 [.020] 0.25 [.010] (ISOLATED BASE) NOT ES: 1. 2. 3. 4.
