The output, constructed with an efficient MOSFET
switch and photovoltaic die, uses Clare’s patented
OptoMOS architecture while the input, a 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 DC switching
applications.

The unique i4-PAC package pioneered by IXYS
enables solid state relays to achieve the highest load
current and power ratings. This package features an
IXYS unique process where the silicon chips are soft
soldered onto the Direct Copper Bond (DCB)
substrate instead of the usual copper leadframe. The
