Description/ Features
The 120NQ...(R) high current Schottky rectifier module series
has been optimized for very low forward voltage drop, with
moderate leakage. The proprietary barrier technology allows
for reliable operation up to 150° C junction temperature.
Typical applications are in switching power supplies, convert-
ers, free-wheeling diodes, and reverse battery protection.
150° C TJ operation
Unique high power, Half-Pak module
Replaces two 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
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
