SCHOTTKY RECTIFIER
35 Amp
35CLQ045
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.
