Description/Features
This center tap Schottky rectifier series has been optimized for
low reverse leakage at high temperature. The proprietary
barrier technology allows for reliable operation up to 175°C
junction temperature. Typical applications are in switching
power supplies, converters, free-wheeling diodes, and reverse
battery protection.
175° C TJ operation
Center tap configuration
Low forward voltage drop
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
