The 72CPQ030PbF center tap Schottky rectifier series 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 battery protection.
