A p–n diode is a type of semiconductor diode based upon the p–n junction. The diode conducts current in only one direction, and it is made by joining a p -type semiconducting layer to an n -type semiconducting layer.
A diode is a two- terminal electronic component that conducts current primarily in one direction (asymmetric conductance ). It has low (ideally zero) resistance in one direction and high (ideally infinite) resistance in the other. Quick Facts Type, Pin configuration ...
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.
Silicon diode - Silicon is the most common material used to make diodes. Silicon has a typical forward voltage of 0.6 − 0.7 V . Germanium diode - Made from a different element. Germanium diodes have a lower forward voltage of 0.25 − 0.30 V . Schottky diode - Made from a silicon-to-metal contact.
The Schottky diode (named after the German physicist Walter H. Schottky ), also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action.
A Zener diode is a special type of diode designed to reliably allow current to flow "backwards" (inverted polarity) when a certain set reverse voltage, known as the Zener voltage, is reached. Zener diodes are manufactured with a great variety of Zener voltages and some are even variable.
Apr 12, 2017 · The diode is one of the oldest and most important electronic devices, although it is not as famous as its cousin, the transistor. Used in all sorts of electrical and electronic systems, the diode functions as a one-way valve for electric current—it only allows current to flow in one direction.
