| PD -20350C SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 8EQ045 10A, 45V Major Ratings and Characteristics Characteristics IF(AV) VRRM IFSM @ tp = 8.3ms half-sine VF @ 10Apk, TJ =125C 8EQ045 10 45 250 0.58 Units A V A V C Description/Features The 8EQ045 Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermetic isolated LCC-18 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 controlled drawings to TX, TXV and S levels. * * * * Hermetically Sealed Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long Term Reliability * Suface Mount * Lightweight TJ, Tstg Operating and storage -55 to 150 Case Style PIN LAYOUT LEGEND A = ANODE C = CATHODE NC = NO CONNECTION Case Outline and Dimensions - LCC-18 www.irf.com 1 05/23/02 8EQ045 Voltage Ratings Part number VR Max.
