Available
RoHS*
COMPLIANT
• High purity, high temperature epoxy
encapsulation for enhanced mechanical strength and
moisture resistance

DESCRIPTION
The 25CTQ.. center tap Schottky rectifier series has been
optimized 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,
freewheeling diodes, and reverse battery protection.
