Description/Features
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
• ESD Rating: Class 3A per MIL-STD-750, Method 1020
