Description/Features
This 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 bat-
tery protection.
150° C TJ operation
Center tap TO-220, D2Pak and TO-262 packages
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)
