Description/ Features
40 Amp
The 40CPQ... center tap Schottky rectifier has been opti-
mized for low reverse leakage at high temperature. The
proprietary barriertechnology allows for reliable operation up
to 175° C junction temperature. Typical applications are in
switching power supplies, converters, free-wheeling diodes,
and reverse battery protection.
. 175° C To operation
. Center tap TO-247 package
. High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
. Low forward voltage drop
. High frequency operation
. Guard ring for enhanced ruggedness and long term
reliability
