Major Ratings and Characteristics
The 203CNQ.. 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 175 °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.
175 °C TJ operation
Center tap module
Low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
