The 40CTQ.. center tap Schottky rectifier has been optimized
for very low forward voltage drop, with moderate leakage.
The proprietary barrier technology 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.
