CONF ORMS TO JEDE C OUTLINE T O-254AA. PD -20358E The 22DGQ045 (series doubler) Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermetic isolated TO-254AA 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  High Frequency Operation  Guard Ring for Enhanced Ruggedness and Long Term Reliability  Schottky Diodes Connected in Series  Electrically Isolated
