Difference Between Diode and Rectifier

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 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, 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.
