Who Does a Diode Work?

The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction), while blocking it in the opposite direction (the reverse direction). As such, the diode can be viewed as an electronic version of a check valve.

What is a diode used for?

Conducting an electric current in one direction

Despite being nothing more than a simple two-pin semiconductor devices, diodes are vital to modern electronics. Some of their most common applications include turning AC to DC, isolating signals from a supply, and mixing signals.

What does a diode control?

The diode is well known for its ability to control the flow of electrical current in a circuit. Unlike passive components that sit idly by resisting or storing, diodes actively have their hands deep in the ebb and flow of current as it courses throughout our devices.
