Description/ Features
The MBR4045WT center tap Schottky rectifier has been opti-
mized for very low forward voltage drop, with moderate leakage.
The proprietary barrier technology allows for reliable 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
