Major Ratings and Characteristics
Characteristics 10CTQ150L Units
Description/Features
The 10CTQ150L center tap Schottky rectifier has been opti-
mized 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.
