The 1N7071CCT8 center tap Schottky rectifier has been
expressly designed to meet the rigorous requirements of
high reliability environments. It is packaged in the hermetic
isolated TO-258AA 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.
