Types of Diode

Diodes are used to protect circuits by using electrical power restrictions and converting AC to DC. Semiconductors such as silicon and germanium are used to make diodes. Or they transmit power in one way, and the way they transmit it is different. There are different types of diodes, and each type has its own system.
