Description/ Features
The 249NQ...(R) high current Schottky rectifier module series
has been optimized for low reverse leakage at high tempera-
ture. The proprietary barrier technology allows for reliable
operation up to 175° C junction temperature. Typical applica-
tions are in switching power supplies, converters, free-
wheeling
175° C T
Unique high power, Half-Pak module
Replaces four 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
