Ordering Information

Pin Configuration

The CPC1972 is an AC Solid State Switch using

optical coupling with dual power silicon controlled

rectifier (SCR) outputs to produce an alternative to

optocoupler and Triac circuits. The CPC1972 switches

are robust enough to provide a blocking voltage of up

to 800V

P .

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

rms of isolation and noise immunity

between the control and load circuits. As a result the

CPC1972 is well suited for industrial environments

where electromagnetic interference could disrupt the

operation of electromechanical relays.
