DESCRIPTION
PRODUCT SUMMARY
The 20CTQ...PbF 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 175 °C junction temperature. Typical
applications are in switching power supplies, converters,
freewheeling diodes, and reverse battery protection.
