What is a Rectifier diode?

A rectifying diode is a semiconductor element that rectifies alternating current from a commercial power supply in a power supply circuit to obtain pulsating current. Compared to general small-signal diode diodes, they are characterized by their large size, high current flow, high withstand voltage, and robust structure. Diodes, which are vacuum tubes, are also called diodes, and were once widely used as rectifiers, but now they are limited to special applications, so this article will be limited to semiconductor devices.
