Description/Features
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
