The 16SCYQ030C 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 resonent
power converters. Full MIL-PRF-19500 quality
conformance testing is available on source control
drawings to TX, TXV and S quality levels.
TJ,Tstg Operating and storage -55 to 150 °C
• Hermetically Sealed
• Center Tap
• Ceramic Eyelets
• Low Forward Voltage Drop
• High Frequency Operation
• Guard Ring for Enhanced Ruggedness and Long
term Reliability
• Lightweight
