The center tap Schottky rectifier module has been optimized
for ultra low forward voltage drop specifically for the OR-ing of
parallel power supplies. The proprietary barrier technology
allows for reliable operation up to 125 °C junction temperature.
Typical applications are in parallel switching power supplies,
converters, reverse battery protection, and redundant power
subsystems.
125°C TJ operation (VR < 5V)
Center tap module
Optimized for OR-ing applications
Ultra low forward voltage drop
High frequency operation
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
Through-hole versions are currently available for use in
Lead-Free applications ("PbF" suffix)
