SCHOTTKY RECTIFIER 35 Amp
12CLQ150
The 12CLQ150 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, or S levels. Typical
applications include switching power supplies and
resonant power converters.
• Hermetically sealed
• Low forward voltage drop
• Center tap
• High frequency operation
• Guard ring for enhanced ruggedness and long term
reliability
• Surface Mount
• Lightweight
