INTEGRATED CIRCUITS DIVISION Parameter Blocking Voltage Load Current On State Voltage Drop Rating 400 500 1.4 Units VP mArms Vrms (at IL = 500mArms) Features Load Current up to 0.5Arms 400VP Blocking Voltage 5mA Sensitivity Zero-Crossing Detection DC Control, AC Output Optically Isolated Low EMI and RFI Generation High Noise Immunity Flammability Rating UL 94 V-0 Applications Programmable Control Process Control Power Control Panels Remote Switching Gas Pump Electronics Contactors Large Relays Solenoids Motors Heaters CPC1943 Optically Coupled AC Power Switch Description The CPC1943 is an AC Solid State Switch using optical coupling with dual power SCR outputs to produce an alternative to optocoupler and Triac circuits. The CPC1943 switches are robust enough to provide a blocking voltage of up to 400VP . 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 3750Vrms of isolation and noise immunity between control and load circuits. As a result the CPC1943 is well suited for industrial environments where electromagnetic interference could disrupt the operation of electromechanical relays.
