• Center tap TO-220, D2PAK and TO-262
packages
Pb-free
Available
• Low forward voltage drop
RoHS*
• High frequency operation
COMPLIANT
• High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance

DESCRIPTION
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, freewheeling diodes, and reverse
battery protection.
