One-way switch
- A diode is a specialized electronic component that acts as a one-way switch. It conducts electric current in only one direction and restricts current from the opposite direction. A diode is reverse biased when it acts as an insulator and is forward biased when it allows current to flow. A diode has two terminals, the anode and the cathode.

A diode is the simplest possible semiconductor device, and is therefore an excellent beginning point if you want to understand how semiconductors work. In this article, you'll learn what a semiconductor is, how doping works and how a diode can be created using semiconductors. But first, let's take a close look at silicon.
A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. [4] It has an exponential current–voltage characteristic. Semiconductor diodes were the first semiconductor electronic devices.
Electronics. Definition. diode. By. TechTarget Contributor. A diode is a specialized electronic component with two electrodes called the anode and the cathode. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium.
Apr 8, 2024 · diode, an electrical component that allows the flow of current in only one direction. In circuit diagrams, a diode is represented by a triangle with a line across one vertex. The most common type of diode uses a p - n junction. In this type of diode, one material ( n) in which electrons are charge carriers abuts a second material ( p) in which ...
A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction. Diodes are also known as rectifiers because they change alternating current (ac) into pulsating direct current (dc).
Jan 29, 2020 · At its most simple, a diode is a device that allows current to flow one direction and not the other. Ideally, it lets current flow one direction without any impedance or affect whatsoever while completely stopping all current flow in the other direction, with a clear line between the two states.
