JAN 23 What is a Diode?

A diode is a semiconductor gadget that essentially switches the current in a single direction. While significantly limiting current flow in the opposite direction, it permits easy flow in one direction. Due to their ability to convert alternating current (ac) into pulsing direct current, diodes are sometimes referred to as rectifiers (dc). Type, voltage, and current capability are used to rate diodes. The anode (positive lead) and cathode, the components of a diode, define their polarity (negative lead). The majority of diodes only permit current to flow when the anode is subjected to positive voltage.

What is the Working Principle of Diode?

In order for a diode to function, n-type and p-type semiconductors must interact. There are not many holes and many unbound electrons in an n-type semiconductor. In other terms, we can say that in an n-type semiconductor, the concentration of free electrons is large and the concentration of holes is quite low.

The majority charge carriers and minority charge carriers of an n-type semiconductor are said to be free electrons and holes, respectively. The number of holes in a p-type semiconductor is higher than the number of free electrons. In a p-type semiconductor, holes make up the majority of the charge carriers while free electrons make up the minority.
