IXYS Integrated Circuits Division and IXYS have
combined to bring OptoMOS? technology, reliability
and compact size to a new family of high-power Solid
State Relays.
As part of this new family, the CPC1788 single-pole
normally open (1-Form-A) DC Solid State Power
Relay employs optically coupled MOSFET technology
to provide 2500V rms of input to output isolation.
Features
? 2.45A DC Load Current with 5°C/W Heat Sink
? Low 1.25 ? On-Resistance
The optically coupled outputs, that use patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs 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
