PD -20532E 12CLQ150 SCHOTTKY RECTIFIER HIGH EFFICIENCY SERIES 35A,150V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM (Per Leg) IFSM @ tp = 8.3ms half-sine (Per Leg) VF @ 15Apk, TJ =125°C (Per Leg) Description / Features 12CLQ150 Units 35 A 150 200 V A 0.86 V TJ, Tstg Operating and storage -55 to 150 °C The 12CLQ150 center tap Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It i s 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 controlled drawings to TX, TXV and S levels. • • • • • Hermetically Sealed Center Tap Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long Term Reliability • Surface Mount • Lightweight CASE STYLE (ISOLATED BASE) 2 1 3 ANODE COMMON ANODE CATHODE Case Outline and Dimensions - SMD-1 www.irf.com 1 10/07/02 12CLQ150 Voltage Ratings Part number VR 12CLQ150 Max.
