DescriptionlFeatu res
The 85CNQO15 centertap Schottky rectfermodule has been
optimized for ultra IowfonNard voltage drop specifcally forthe
OR-ing of parallel power supplies. The proprietary barrier
technology allows for reliable operation up to 125 °Cjunction
temperature. Typical applications are in parallel switching
power supplies, converters, reverse battery protection, and
redundant powersubsystems.
. 125°C T, operation (V,, < 5V)
. Centertap module
. Optimized forOR-ing applications
. Ultra Iowforward voltage drop
. Highfrequencyoperation
. Guard ring forenhanced ruggedness and long term
reliability
. High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
