Major Ratings and Characteristics
The 440CNQ030 center tap, high current, Schottky rectifier
module has been optimized for very low forward voltage drop,
with moderate leakage. The proprietary barrier technology
allows for reliable operation up to 150 C junction tempera-
ture. Typical applications are in switching power supplies,
converters, free-wheeling diodes, welding and reverse bat-
tery protection.
