35 Amp

The 35CLQ045 center tap Schottky rectifier has been expressly designed to meet the rigorous requirements of hi -rel environments. It is packaged in the hermetic surface mount SMD-1 ceramic package and has extremely low reverse leakage at high temperature. Full MIL-PRF-19500 quality conformance testing is available on source control drawings to JANTX, JANTXV and S levels.Typical applications include switching power supplies and resonant power converters.
