PD-91855B 15LJQ100 JANS1N6844U3 JANTX1N6844U3 JANTXV1N6844U3 15A, 100V SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES REF: MIL-PRF-19500/679 Major Ratings and Characteristics Description/Features Characteristics Limits IF(AV) Rectangular Waveform 15 A VRRM 100 V IFSM @tp = 8.3ms half-sine 250 A VF @15Apk, TJ =125°C 0.72 V The1N6844U3 Schottky rectifier has been expressly designed to meet the rigorous requirements of Hirel 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 controlled drawings to S, TX and TXV levels. TJ, Tstg Operating and Storage -65 to 150 Units °C • Hermetically Sealed • Low Forward Voltage Drop • High Frequency Operation • Guard Ring for Enhanced Ruggedness and Long Term Reliability • Surface Mount • Lightweight CASE STYLE ( ISOLATED BASE ) CATHODE ANODE ANODE Case Outline and Dimensions - SMD-0.5 www.irf.com 1 09/08/05 15LJQ100, 1N6844U3 Voltage Ratings Part number VR VRWM 1N6844U3 Max.
