Major Ratings and Characteristics
Description/ Features
The20CTQ...PbFcentertapSchottkyrectifierserieshasbeen
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, free-wheeling diodes,
and reverse battery protection.
