HIGH EFFICIENCY SERIES
The 35GQ150 Schottky rectifier has been expressly
designed to meet the rigorous requirements of HiRel
environments. It is packaged in the hermeticly 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
• Low Forward Voltage Drop
• High Frequency Operation
• Guard Ring for Enhanced Ruggedness and Long term
Reliability
• Lightweight
