Major Ratings and Characteristics Description/ Features
The 183NQ high current 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 switching power supplies, converters, free-wheeling
diodes, and reverse battery protection.
175° C TJ operation
Unique high power, Half-Pak module
Replaces three parallel DO-5's
Easier to mount and lower profile than DO-5's
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
