Major Ratings and Characteristics Description/Features
The MBR6045WTPbF center tap Schottky rectifier has been
optimized for very low forward voltage drop, with moderate
leakage. The proprietary barrier technology allows for reli-
able operation up to 150° C junction temperature. Typical
applications are in switching power supplies, converters,
free-wheeling diodes, and reverse battery protection.
150° C TJ operation
Center tap TO-247 package
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
Lead-Free ("PbF" suffix)
