PD - 94288A SCHOTTKY RECTIFIER 30LJQ045 HIGH EFFICIENCY SERIES 30 Amp, 45V Major Ratings and Characteristics Characteristics Description/Features 30LJQ045 Units IF(AV) 30 A VRRM 45 V IFSM @ tp = 8.3ms half-sine 100 A VF @ 30Apk, TJ =125°C 0.66 V TJ, Tstg Operating and storage -55 to 150 °C The 30LJQ045 Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermetic surface mount SMD-0.5 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 Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long term Reliability • Surface Mount • Lightweight CASE STYLE CATHODE ANODE ANODE IR Case Style SMD-0.5 www.irf.com 1 08/21/01 30LJQ045 Voltage Ratings Part number VR 30LJQ045 Max.
