The optically coupled outputs, that use patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED. The combination of low
on-resistance and high load current handling
capability makes this relay suitable for a variety of high
performance DC switching applications.

The unique ISOPLUS-264 package pioneered by
IXYS enables Solid State Relays to achieve the
highest load current and power ratings. This package
features a unique IXYS process where the silicon
chips are soft soldered onto the Direct Copper Bond
(DCB) substrate instead of the traditional copper
leadframe. The DCB ceramic, the same substrate
used in high power modules, not only provides
