The CPC1972 is an AC solid state switch with optically isolated input and dual SCR output for AC load control up to 250 mA rms at 800 V blocking voltage. It features zero-crossing detection to minimize transients and is supplied in a 6-pin DIP package. The device provides 3750 Vrms isolation between input and output, with a maximum on-state voltage drop of 3 V at 250 mA rms and a sensitivity of 5 mA to activate the LED input. It is UL recognized and CSA certified, with an operating temperature range of -40°C to +85°C.
The OptoMOS® line of power products uses dual power SCR outputs to produce an alternative to optocoupler and Triac circuits. These switches provide a blocking voltage of up to 800V. 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 up to 5000Vrms of isolation and noise immunity between control and load circuits. Long life and environmental integrity make these power switches ideal for controlling a variety of AC circuits in industrial environments where electromagnetic interference would disrupt the operation of electromechanical relays. Load Currents up to 5 A Voltage Controlled Devices Available Blocking Voltage from 400 V to 800 V 5 mA Drive Input Sensitivity Zero-Crossing Detection Dc control and ac output Optically Isolated I/O TTL and CMOS Compatible Low EMI and RFI Generation High Noise Immunity
