Name any two types of diodes with their one application.

Answer:
P-N Junction Diode
The P-N junction diode is made up of semiconductor material. It consists of two layers of semiconductors. One layer is doped with P-type material and the other layer with N-type material. The combination of these both P and N-type layers form a junction known as the P-N junction. Hence the name P-N junction diode.
It allows the flow of current in the forward direction and blocks it in reverse direction. They are also known as rectifier diode used for rectification.
There are different types of diodes that use the P-N junction with variation in doping concentration. They are discussed below.
Small Signal Diode
It is a type of P-N junction diode which operates on low voltage signals. Its junction area is very small. Due to which, the junction has less capacitance & low charge storing capacity. It enables the small signal diode to have high switching speed with very fast recovery time. However, its limitations are low voltage and current parameters.
Due to its high switching speed, these types of diodes are used in circuits with high frequencies.
