Various semiconductor diodes. Left: A four-diode bridge rectifier. Next to it is a 1N4148 signal diode. On the far right is a Zener diode. In most diodes, a white or black painted band identifies the cathode …

Dec 12, 2025 · Diode, an electrical component that allows the flow of current in only one direction. The most common type of diode uses a p-n junction in which one material (n) has electrons as charge …

Dec 3, 2024 · Learn how diodes -- a specialized electronic component, or two-terminal semiconductor device -- work, plus construction, use cases and the types of diodes.

Diodes have numerous applications across the electronic industry, and they are an integral part of any electronic device. In this video, we will explore the ...

Diodes have two terminals, anode and cathode. Whether current flows or not depends on the direction of voltage applied to these terminals. This operation is called rectification and is the basic operation …

Learn about diodes and diode circuits from CircuitBread. A diode is a two-terminal semiconductor device formed by two doped regions of silicon divided by a pn junction.

What Is a Diode? Diodes are used to protect circuits by limiting the voltage and to also transform AC into DC. Semiconductors like silicon and germanium are used to make the most of the diodes. Even …
