Major Ratings and Characteristics
The 200CNQ center tap Schottky rectifier module series has
been optimized for low reverse leakage at high temperature.
The proprietary barrier technology allows for reliable opera-
tion up to 150 C junction temperature. Typical applications
are in high current switching power supplies, plating power
supplies, UPS systems, converters, free-wheeling diodes,
welding, and reverse battery protection.
