Optically Isolated AC Solid State Power Switches

The CPC1961G is a dual pole AC solid state Switch that uses optical coupling with dual monolithic SCR outputs to produce an alternative to Optocoupler and Triac circuits. The CPC1961G switches are robust enough to provide a blocking voltage of up to 600V. In addition, tightly controlled zero cross circuitry ensures switching of AC loads without the generation of transients. The input and output circuits are optically coupled to provide 3750V of isolation and noise rms immunity between control and load circuits. As a result the CPC1961G is well suited for industrial environments where electromagnetic interference would disrupt the operation of electromechanical relays. The CPC1961G is offered in a space saving 8 pin DIP package with two independent switches. By Clare, Inc.
