Major Ratings and Characteristics
The 201CMQ center tap, high current, Schottky rectifier
module series has been optimized for very low forward voltage
drop, with moderate leakage. The proprietary barrier technol-
ogy allows for reliable operation up to 175 °C junction tem-
perature. Typical applications are in switching power sup-
plies, converters, free-wheeling diodes, and reverse battery
protection.
175 °C TJ operation
Center tap module
High purity, high temperature epoxy encapsulation for
enhanced mechanical strength and moisture resistance
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
