IF(AV) = 20Amp
VR = 35/ 45V
Description/Features
Major Ratings and Characteristics
The 20CTQ 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, free-wheeling diodes,
and reverse battery protection.
