Applications of Diode

Diodes are the two-terminal components used in many electronics and electrical applications. The current flow in such components is unidirectional. A diode provides very low resistance in one direction, but in the opposite direction, it provides very high resistance. One of the common functions of a diode is to allow the current flow in the forward direction and resist the current flow in the reverse direction. However, besides this simple functioning of diodes, diodes generally show non-linear current-voltage characteristics. For instance, the semiconductor diodes conduct current only when a certain threshold voltage, or preferably cut-off voltage is reached in the forward direction. They are known as forward-biased diodes. Also, upon reaching a certain voltage, known as the breakdown voltage, the high resistance provided by diodes in the reverse direction reaches a low resistance value.
