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 new family, the CPC1779 single-pole

normally open (1-Form-A) DC Solid State Power

Relay employs optically coupled MOSFET technology

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 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

used in high power modules, not only provides

thermal resistance (0.3 °C/W).
