These AC power solid state switches use dual power SCR outputs. Tightly controlled zero cross circuitry also ensures low noise switching of AC loads by minimizing the generation of transients. Optically coupled input and output circuits provide 2500 Vrms of isolation. This also includes noise immunity between control and load circuits. This makes them ideally suited to applications where electromagnetic interference could disrupt the operation of electromechanical relays.

The unique SuperSIP package allows these units to achieve the highest load current currently available in a similar sized package. This package is manufactured with the silicon chip being soft soldered onto the Direct Copper Bond (DCB) substrate rather than the traditional copper lead frame. These DCB ceramics are what makes it possible to provide 2500 Vrms isolation but still offer a very low junction-to-case thermal resistance from only 0.35°C per watt.
