Diode - Wikipedia
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. A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction connect… 展开

A diode is a two-terminal electronic component that primarily conducts electricity in one direction. It has low resistance in one direction (forward direction) and high resistance in the opposite direction (reverse direction). This unidirectional behavior makes diodes essential in various electronic applications12.
Construction and Symbol
Diodes are typically made from semiconductor materials such as silicon or germanium. The diode symbol consists of an arrowhead pointing towards a line. The arrowhead represents the anode (positive terminal), and the line represents the cathode (negative terminal). The direction of the arrow indicates the direction of conventional current flow when the diode is forward-biased13.
Types of Diodes
There are several types of diodes, each with specific characteristics and applications:
