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 family, the CPC1979 single-pole
normally open (1-Form-A) Solid State Power Relay is
rated for up to 3.5A rms continuous load current with a
5°C/W heat sink.
Features
? 3.5A rms Load Current with 5°C/W Heat Sink
? Low 0.75 ? On-Resistance
? 600V P Blocking Voltage
The CPC1979 employs optically coupled MOSFET
technology to provide 2500V rms of input to output
isolation. 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 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
