A diode is a nonlinear circuit element. A diode is an electronic component that allows the current to flow in only one direction. It is a two-terminal semiconductor device. The 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 to to the conversion.
Differences between a Diode and a Rectifier
Let us look at more differences between them to understand them better.
|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 convert 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, photodiode, 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 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.
