The CPC1945Y is an AC solid state relay with zero-crossing detection, designed for switching AC loads up to 1 A rms at 120 V rms. It features optically isolated input and output circuits with 3750 V rms isolation, a 400 V peak blocking voltage, and a 1.6 V on-state voltage drop at 1 A rms. The device is packaged in a 4-pin SIP with an 8-pin body, measuring 19.202 mm in length and 5.08 mm in width. It operates from -40°C to +85°C and is UL recognized, CSA certified, and compliant with EN IEC 62368-1. It requires 5 mA input current for activation and supports switching frequencies from 20 to 400 Hz.
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
