CPC1943G - AC Power Switch

Download the CPC1943G datasheet PDF. This datasheet also covers the CPC1943 variant, as both devices belong to the same ac power switch family and are provided as variant models within a single manufacturer datasheet.

General 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 .

Key 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.
