The 1N7045T3 Schottky rectifier has been expressly designed to meet the rigorous requirements of high reliability environments. It is packaged in the hermetic isolated TO-257AA 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 levels. • • • •
Hermetically Sealed Low Forward Voltage Drop High Frequency Operation Guard Ring for Enhanced Ruggedness and Long Term Reliability • Lightweight • Ceramic Eyelets • ESD Rating: Class 3A per MIL-STD-750, Method 1020
