The signal from ac mains is fed into a step down transformer T which makes it available at the terminals X and Y. It is a special type of diode which operates in the breakdown region. One type that is used for a variety of circuits is the PIN diode. Devices, invariably have clear instructions about using AC/DC current. 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. The way that a diode operates can be difficult to understand as it involves fairly advanced quantum mechanics.However, at the simplest level the operation of a diode can be understood by looking at the flow of positive charges (or "holes") and the negative charges (the electrons).Technically, a semiconductor diode is referred to as a p-n junction.

Diodes are used in clamping circuits for DC restoration. Until now, we have mentioned only one application for the diode-rectification, but there are many more applications that we have not yet discussed. The positive side of a diode is known as the anode and the negative side is known as the cathode.. Current can spill out of the anode end to the cathode, but it cannot pass from cathode to the anode. Diodes are divided into two types based on the formation of the junction between the terminals. Applications of PN junction diode 1. A p-n junction diode allows electric current when it is forward biased and blocks electric current when it is reverse biased. • This form of diode is used in a number of areas.
