Description/Features
The Schottky rectifier module has been optimized for ultra low
forward voltage dropspecifcallyforthe OR-ing of parallel power
supplies. The proprietary barriertechnology 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 N,, < 5V)
. Single diode configuration
. Optimized for OR-ing applications
. Ultra Iowforward voltage drop
. Guard ring forenhanced ruggedness and long term
reliability
. High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
