| PD -93972 SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 80SCLQ045 80 Amp, 45V Major Ratings and Characteristics Characteristics IF(AV) VRRM (Per Leg) IFSM @ tp = 8.3ms half-sine (Per Leg) VF @ 40Apk, TJ =125C (Per Leg) 80SCLQ045 Units 80 45 A V Description/Features The 80SCLQ045 center tap Schottky rectifier has been expressly designed to meet the rigorous requirements of hirel environments. It is packaged in the hermetic surface mount SMD-1 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 power converters. Full MIL-PRF-19500 quality conformance testing is available on source control drawings to TX, TXV and S quality levels. * * * * * Hermetically Sealed Center Tap Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability * Surface Mount * Lightweight 250 0.62 A V TJ, Tstg Operating and storage -55 to 150 C CASE STYLE 2 1 3 ANODE COMMONANODE CATHODE IR Case Style SMD-1 www.irf.com 1 10/06/00 80SCLQ045 Voltage Ratings Part number VR Max.
