Description/Features The 8CLJQ045 center tap 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 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
