Description/ Features
The 400CNQ center tap, high current, Schottky rectifier
module series 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
temperature. Typical applications are in switching power
supplies, converters, free-wheeling diodes, welding, and re-
verse battery protection.
