Other optocouplers

Optocouplers are electronic devices that serve to galvanically isolate electrical circuits. Separate components serve as the mechanism for converting an electrical signal in an optocoupler. An LED as an emitter, and a photodetector, in the form of a photodiode, phototransistor, photoresistor, photothyristor or photodinistor. It is the optical intrastructural elements of the optocoupler that determine its class and operating capabilities.

You can choose and buy the necessary optocoupler according to the existing catalog, namely, by the name of the component. However, a table with technical parameters will help you choose an analogue of the missing product. The first thing that determines interchangeability is the body type and the number of channels, respectively. The optocoupler output element type determines the output current, voltage, and maximum output power of the optocoupler.

Optocouplers have found wide application in various fields of electronics. Any modern switching power supply contains an optocoupler in the control circuit, which controls the voltage of the secondary circuits. Vishay, Sharp, Toshiba components, such as PC 120, PC 123, PC 817, CNY 74, PC 111, have quality indicators.

Russian optocouplers of Proton OJSC are distinguished by a high current gain due to a powerful output composite phototransistor. Russian-made dinistor optocouplers AOU103, AOU115 are used as keys in electronic circuits, and protection devices for secondary circuits of power supplies.
