SCHOTTKY RECTIFIER
35 Amp, 60V
35SCGQ060
The 35SCGQ060 center tap Schottky rectifier has been
expressly designed to meet the rigorous requirements of
hirel environments. It is packaged in the hermetic isolated
TO-254AA package. The device's forward voltage drop
and reverse leakage current are optimized for the lowest
power loss and the highest circuit efficiency for typical high
frequency switching power supplies and resonent power
converters. Full MIL-PRF-19500 quality conformance
testing is available on source control drawings to
TX, TXV and S quality levels.
• Hermetically Sealed
• Center Tap
• Low Forward Voltage Drop
• High Frequency Operation
• Guard Ring for Enhanced Ruggedness and Long term
Reliability
• Lightweight
