Power relay, CPC1979J, LITTELFUSE

A single-pole normally open solid state power relay is rated for up to 3.5 Arms continuous load current with a 5°C/W heat sink, and with IXYS integrated circuits, it brings OptoMOS technology, reliability and compact size. It employs optically coupled MOSFET technology to provide 2500 Vrms of input to output isolation. The optically coupled outputs, which use the 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 softly 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 2500 Vrms isolation but also very low junction-to-case thermal impedance (0.3 °C/W).
