Diode is a nonlinear circuit element. Diode is an electronic component that allows the current to flow in only one direction. It is a two terminal semiconductor device. Rectifier is a device that is used to convert an AC voltage to a DC voltage. A diode is used as a switch and a rectifier is used for the conversion of an AC voltage to a DC voltage.
Differences between a Diode and a Rectifier
Let us look at more differences between them to understand better.
|
Diode |
Rectifier |
|---|---|
|
A diode conducts current when it is forward biased and blocks the flow of current when reverse biased. |
A rectifier circuit consists of a diode, a step down transformer and a filter circuit which collectively converts AC to DC. |
|
The current carrying capability is low in a diode. |
The current carrying capability is high in a rectifier. |
|
Diodes are used in switches, clampers, clippers, etc. |
Rectifiers are used in computers, batteries,etc. |
|
Zener diode, photo diode, etc. are the different types of diodes. |
Single phase rectifiers and three phase rectifiers are the two types of rectifiers. Single phase rectifiers are further divided into half wave and full wave rectifiers. |
The difference between between a diode and a rectifier should be understood clearly as it is an important and fundamental concept in electronics. To Know more about zener diode, photodiodes,etc. Visit BYJU’S.
