PD - 94396 SCHOTTKY RECTIFIER 120LQ100 HIGH EFFICIENCY SERIES 120 A, 100V Major Ratings and Characteristics Characteristics Description/Features 120LQ100 Units IF(AV) 120 A VRRM 100 V IFSM @ tp = 8.3ms half-sine 1000 A VF @ 120Apk, TJ =125°C 0.74 V TJ,TstgOperating and storage -55 to 150 °C The 120LQ100 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 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 Case Outline and Dimensions - SMD-1 www.irf.com CATHODE ANODE ANODE 1 03/15/02 120LQ100 Voltage Ratings Part number VR 120LQ100 Max.
