The ORPC-852 is a photo coupler featuring a high voltage photo Darlington detector coupled with an infrared emitting diode. It offers high collector-emitter voltage (350V), a high current transfer ratio (MIN. 1000%), and high isolation voltage (5000 Vrms). This RoHS and REACH compliant device is suitable for applications requiring signal transmission between circuits of different potentials and impedances, such as telephone sets, system appliances, and sequence controllers.
