Vishay High Power Products
FEATURES
150 °C TJ operation
Center tap TO-220 package
Low forward voltage drop
High frequency operation
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
Guard ring for enhanced ruggedness and long term
reliability

DESCRIPTION
The MBR15..CT center tap 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, freewheeling diodes,
and reverse battery protection.
