Description/Features
The MBR7.. Schottky rectifier has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 150° C junction temperature. Typical applications are in switching power supplies,converters,free-wheelingdiodes,andreversebattery protection.
150° C TJ operation
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
