The center tap Schottky rectifier module has been optimized
for ultra low forward voltage drop specifically for 3.3V output
power supplies. The proprietary barrier technology allows for
reliable operation up to 150 °C junction temperature. Typical
applications are in parallel switching power supplies,
converters, reverse battery protection, and redundant power
subsystems.
Guard ring for enhanced ruggedness and long term
reliability
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
New fully transfer-mold low profile, small
footprint, high current package
