Major Ratings and Characteristics Description/Features
The 1N7047CCT3 center tap Schottky rectifier has
been expressly designed to meet the rigorous
requirements of high reliability environments. It is
packaged in the hermetic isolated TO-257AA
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
resonant power converters. Full MIL-PRF-19500
quality conformance testing is available on source
controlled drawings to TX, TXV and S levels.
• Hermetically Sealed
• Center Tap
• Low Forward Voltage Drop
• High Frequency Operation
• Guard Ring for Enhanced Ruggedness and Long
Term Reliability
• Electrically Isolated
