Major Ratings and Characteristics

The 203CNQ... (R) center tap Schottky rectifier module series

has been optimized for low reverse leakage at high tempera-

ture.

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

High purity, high temperature epoxy encapsulation for

enhanced mechanical strength and moisture resistance

Low forward voltage drop

High frequency operation

Guard ring for enhanced ruggedness and long term

reliability
