PD-20504C SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 60LQ045 60A, 30V Major Ratings and Characteristics Characteristics IF(AV) VRRM IFSM @ tp = 8.3ms half-sine VF @ 60Apk, TJ =125C 60LQ045 60 45 400 0.6 Units A V A V C Description/Features The 60LQ045 Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel 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 resonant power convertors. Full MIL-PRF-19500 quality conformance testing is availble on control drawings to TX, TXV and S quality levels. * * * * Hermetically Sealed Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability * Surface Mount * Lightweight TJ, Tstg Operating and storage -55 to 150 CASE STYLE CATHODE ANODE ANODE Case Outline and Dimensions - SMD-1 www.irf.com 1 03/20/02 60LQ045 Voltage Ratings Part number VR Max.
