Units

The 181NQ high current Schottky rectifier module series has been optimized for very low forward voltage drop, with moder-ate leakage. 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 T J

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 Very low forward voltage drop

High frequency operation

Guard ring for enhanced ruggedness and long term
