What is photocoupler or optocoupler?
A photocoupler, also known as an optocoupler, is an electronic component used to transmit electrical signals between isolated circuits using light. It typically consists of an LED (light-emitting diode) and a photodetector (like a phototransistor or photodiode) enclosed in a single package and separated by an optically transparent barrier.
How optocouplers work in circuits | Description, Example
The optocoupler''s electrical isolation is achieved because the LED and photodetector are physically separated by the dielectric material, and there is no direct electrical connection between them. Therefore, any voltage or current changes on one side of the optocoupler do not affect the other side.
Understanding Phototransistor Optocouplers
An optocoupler, also known as photo-coupler or opto-isolator, is a component which can transfer an electrical signal across two galvanically¬-isolated circuits by means of optical coupling. They offer high isolation ratings (5 kV) in a very compact form-factor and, unlike transformers and capacitors which can only transfer AC signals, …
