45A*, 100V 45CKQ100 Major Ratings and Characteristics Description/Features 02/26/02 CASE STYLE www.irf.com 1 Characteristics 45CKQ100 Units IF(AV) Rectangular 45* A waveform VRRM (Per Leg) 100 V IFSM @ tp = 8.3ms half-sine 400 A (Per Leg) TJ, T stg Operating and storage -55 to 150 °C ANODE COMMON ANODE CATHODE 1 23 HIGH EFFICIENCY SERIES IR Case Style TO-258AA PD -20355C 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 (ISOLATED BASE) VF @ 25Apk, TJ =125°C 0.74 V (Per Leg) *IF(AV) current is limited by pin diameter NOT E S : 1.
