Description/Features
The 1N609. Schottky rectifier has been optimized for very low
forward voltage drop, with moderate leakage. The proprietary
barrier technology allows for reliable operation up to 125° C
junction temperature. Typical applications are in switching
power supplies, converters, free-wheeling diodes, and reverse
battery protection.
125° C TJ operation
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
Hermetic packaging
