An optocoupler, also called an optoisolator, is a component whose function is to provide an electrically isolated connection between two circuits with different voltages. In this way, it acts as a switch that is activated by the infrared light from a LED diode and, when it stops, it opens.

But what specifically is this article for?It is responsible for preventing voltage peaks or high voltages at the input of the circuit that can seriously damage it. It prevents the use of relays, mechanical noise in systems and bounce signals from other electrical circuits.

Buying an optocoupler at Icompplus will ensure you a quality material that you will not find in any other online store of passive components., and will allow you to have quick access to other useful elements such as the connectors or semiconductors..

Before deciding what type of optocoupler you want to purchase, it is important that you know how it works, since it is a procedure that, although complicated to understand at first, is very simple. We explain it to you:

The current reaches the component from its input,which makes the LED diode react, which will turn on a light proportional to the volume of electricity; then, this reaches the capsule and the photosensor, which will switch to saturation and will allow this current to continue to flow.

In this way, it works as a switch that lets or does not let electricity through depending on the amount it reaches; thus, two different circuits connected will not allow high voltages or short circuits.

Thinking about what type of optocoupler you should buy from our online store? These can be differentiated into 4,depending on the output device of the same; these, in turn, are divided into several models available on our web site

Phototransistor

We are talking about the most common component of all; this is formed by a traditional transistor, and controls the direct current for its output. For example: the

Photodarlington

To the original, a Darlington configuration is added, which contains two transistors and allows a large volume of current to pass through.

Phototiristor

It is designed with a thyristor at its output, allowing it to handle large amounts of current and voltage.

Phototriac

Formed by a triac at the output, created to control the alternating current. We would be talking, for example, about the
