Dynamische information

What is an optocoupler? An optocoupler is a valuable semiconductor device that facilitates the electrical signal transmission between two isolated circuits. It offers many advantages, e.g., removing electrical noise from signals, allowing small digital signals to control larger voltages, preventing disruptions from voltage surges, and more. There are many types of the optocoupler. These include photo-transistor, photo-Triac, photo-SCR, and photo-darlington. In terms of product models, PC817 is the most popular optocoupler circuit. This article explores the various features and parameters of PC817 and its alternatives.

 

 

 

Overview of PC817 Optocoupler

PC817 is one of the most popular optocouplers available on the market. It is a standard optocoupler circuit consisting of a photo-transistor and an infrared LED diode that isolates two parts of a circuit and prevents the transmission of unwanted noise and ground loops. In the opto-isolator IC circuit of PC817, the IR LED utilizes the signal with noise as a power from one circuit and then transfers it to another using infrared. The other part receives the signal and then operates according to the specific design of the circuit.

 

The main appeal of this particular optocoupler is its ease of use. It works well in an electronic circuit for a single task. If you need multiple isolation tasks at the same time, you can use 817 optocouplers with other types of optocouplers that contain IR LEDs and photo-transistors.

 

Key Parameters, Features, and Applications of PC817

PC817 has most of the key characteristics of a standard optocoupler circuit, and it also contains its own specific features. Its specifications/parameters are as follows:
