What Is the Function of a Rectifier Diode?

A rectifier diode is used to force electricity to flow only in one direction. These components are commonly used to change alternating current into direct current.

The rectifier diode is a component of a rectifier, which can contain one or more of these diodes. These components are usually made from silicon and serve as discrete parts or are integrated into circuits.

Rectifier diodes only allow electrical current to flow in one direction, from AC to DC, in a process called "rectification." These diodes are vital components in DC power supplies, radios and receivers, high-voltage DC power transmission systems, notebooks, laptops, televisions and more.
