MOSFET switches and photovoltaic die, uses Clare’s
patented OptoMOS architecture while the input, a
highly efficient GaAlAs infrared LED, provides the
optically coupled control. The combination of low
on-resistance and high load current handling
capability makes this relay suitable for a variety of high
performance 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 in which 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
