| PD - 20346C 22CGQ045 SCHOTTKY RECTIFIER 35* Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 8.3ms sine VF @ 20Apk, TJ = 125C (Per Leg) 22CGQ045 35* Units A Desciption/Features The 22CGQ045 center tap 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 and has extremely low reverse leakage at high temperature. Full MIL-PRF-19500 quality conformance testing is available on source controlled drawings to JANTX, JANTXV, or JANS levels. Typical applications include switching power supplies and resonant power converters. * * * * Hermetically sealed Center tap High frequency operation Guard ring for enhanced ruggedness and long term reliability * Electrically isolated * Ceramic eyelets 45 300 0.70 V A V TJ, Tstg Operating and storage -55 to 150 *IF(AV) current limited by pin diameter C CASE STYLE (ISOLATED BASE) NOTES: 1.
