Optocoupler in 60s⚡
*Optocoupler:*
An optocoupler, or opto-isolator, is a component that electrically isolates two parts of a circuit while allowing communication through light.
It consists of a light-emitting diode (LED) and a photodetector, typically a phototransistor or photodarlington. When the LED emits light, the photodetector responds, creating electrical isolation.
Application:
Optocouplers are widely used to transmit signals between different electrical circuits while preventing direct electrical connection. T
hey find applications in signal isolation, voltage level shifting, and noise reduction.
Optocouplers enhance the reliability and safety of electronic systems, especially in scenarios where isolation between high and low-voltage components is essential.
