The 124NQ... (R) high current Schottky rectifier modules have
been optimized for extremely low forward voltage drop, with
higher leakage. The proprietary barrier technology allows for
reliable operation up to 125° C junction temperature. Typical
applications are in switching power supplies, converters, freewheeling diodes, welding, and reverse battery protection.

Unique high power Half Pak module
High purity, high temperature epoxy encapsulation for en
hanced mechanical strength and moisture resistance
Extremely low forward voltage drop
High frequency operation
Guard ring enhanced ruggedness and long term reliability
