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

5ºC/W heat sink.

The CPC1979 employs optically coupled MOSFET

technology to provide 2500V

isolation. The output is constructed with efficient

MOSFET switches and photovoltaic die that use

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 allows 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 used in high power modules, not only

provides 2500V

resistance (0.3 °C/W).
