Description/ Features
The MBR15.. 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, free-wheeling diodes, and reverse battery protection.
150° C TJ operation
Center tap TO-220 package
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
Lead-Free ("PbF" suffix)
