SCHOTTKY RECTIFIER
45* Amp
60CKQ045
The 60CKQ045 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-258 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
• Low Forward Voltage Drop
• Center Tap
• High Frequency Operation
• Guard Ring for Enhanced Ruggedness and Long
Term Reliability
• Electrically Isolated
• Ceramic Eyelets
