Diode: Difference between revisions

Latest revision as of 11:41, 18 February 2025

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. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate.

History[edit]

The first types of diode, the vacuum tube (thermionic) diodes, were invented in 1904 by John Ambrose Fleming, who had been provided with the only sample of a thermionic valve made by Thomas Edison.

Types of Diodes[edit]

There are several types of diodes are available for use in electronics design. Some of them include:

Applications[edit]

Diodes have many applications across a wide range of electronic systems and circuits. Some of the main applications of diodes include:
