JANS1N7043CCT1
JANTX1N7043CCT1
JANTXV1N7043CCT1
The 1N7043CCT1 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-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
