PD -20356D 45CIQ100 SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 45A*, 100V Description/Features Major Ratings and Characteristics Characteristics 45CIQ100 Units IF(AV) Rectangular waveform VRRM (Per Leg) 45* A 100 V 400 A 0.74 V IFSM @ tp = 8.3ms half-sine (Per Leg) VF @ 25Apk, TJ =125°C (Per Leg) TJ, Tstg Operating and storage -55 to 150 *IF(AV) current is limited by pin diameter °C The 45CIQ100 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-259AA 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 • 2 Interdigitated mounting tabs for secured, intimate heatsink contact • Electrically Isolated CASE STYLE (ISOLATED BASE) 1 2 3 ANODE COMMONANODE CATHODE IR Case Style TO-259AA www.irf.com 1 02/27/02 45CIQ100 Voltage Ratings Part number VR 45CIQ100 Max.
