Units VRMS A VRMS (at IL=1.0A)
Features * Load Current up to 1A * Blocking Voltage to 400V * 5mA Sensitivity * Zero-Crossing Detection * DC Control, AC Output * Optically Isolated * TTL and CMOS Compatible * Low EMI and RFI Generation * High Noise Immunity * VDE compatible * Machine Insertable, Wave Solderable
Description The CPC1945Y is a AC Solid State Switch using patented waveguide coupling with dual power SCR outputs to produce an alternative to optocoupler and Triac circuits. The CPC1945Y switches are robust enough to provide a blocking voltage of up to 400V. 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 immunity between control and load circuits. As a result the CPC1945Y is well suited for industrial environments where electromagnetic interference would disrupt the operation of electromechanical relays.

Absolute Maximum Ratings are stress ratings. Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extended period may degrade the device and effect its reliability.
