The IRKCS208.. Schottky rectifier Common Cathode has been optimized
for low reverse leakage at high temperature. The proprietary barrier technol-
ogy allows for reliable operation up to 150°C junction temperature. Typical
applications are in high current switching power supplies, plating power
supplies, UPS systems, converters, free-wheeling diodes, welding, and
reverse battery protection.

Mechanical Description
The Generation V of Add-A-pak module combine the
excellent thermal performance obtained by the usage
of Direct Bonded Copper substrate with superior me-
chanical ruggedness, thanks to the insertion of a solid
Copper baseplate at the bottom side of the device.
The Cu baseplate allow an easier mounting on the
majority of heatsink with increased tolerance of sur-
face roughness and improve thermal spread.
The Generation V of AAP module is manufactured without
hard mold, eliminating in this way any possible direct
stress on the leads.
The electrical terminals are secured against axial pull-out:
they are fixed to the module housing via a click-stop
feature already tested and proved as reliable on other IR
modules.
