Description/Features
The 243NQ high current Schottky rectifier module series has
been optimized for low reverse leakage at high temperature.
The proprietary barrier technology allows for reliable opera-
tion 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 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
