Description/Features
The 121NQ... (R) high current Schottky rectifier module
series has been optimized for low reverse leakage at high
temperature. The proprietary barrier technology allows for
reliable operation 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 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
Low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
