Description

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

5°C/W heat sink.

The CPC1979 employs optically coupled MOSFET

isolation. The optically coupled outputs, that use

patented OptoMOS architecture, are controlled by a

highly efficient 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

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

thermal resistance (0.3 °C/W).
