Major Ratings and Characteristics
Description/ Features
The 32CTQ030PbF 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.
