IXYS Integrated Circuits Division (ICD) has added the CPC1968J optically isolated power solid state relay to its ISOPLUS-264 package of power relays. Currently available in production quantities, the CPC1968J 2Arms power relay has a load voltage rating of at least 400V and continuous load current of up to 5A.

The CPC1968J is a single-pole normally open (1-Form-A) solid state power relay employs optically coupled MOSFET technology to provide 2.5kVrms of input to output isolation. The output is constructed with efficient MOSFET switches and ICD's patented OptoMOS architecture and technology. The CPC1968J combines low on-resistance, high load voltage and high load current handling capability, making it ideal for various high performance switching applications such as medical equipment, industrial controls, electronic switching and instrumentation.

The IXYS ISOPLUS-264 package enables solid state relays to achieve the highest load current and power ratings in a small footprint. It features power silicon devices mounted onto a direct copper bond substrate to maximise power handling capability. This DCB ceramic, the same substrate used in high power modules, not only provides 2.5kVrms isolation but also has a very low thermal resistance of 0.3 degrees C/W.
