Semiconductor diodes are electronic components that primarily serve as one-way electrical gates for current flow. They are typically made of semiconductor materials like silicon and possess two terminals: an anode (positive) and a cathode (negative). The most common type of diode is the pn-junction diode, which allows current to flow in one direction while blocking it in the opposite direction. Semiconductor diodes are commonly used in rectification circuits to convert AC (alternating current) into DC (direct current), such as in power supplies. They also find application in signal clipping, voltage regulation, and protection against reverse voltage or current. Zener diodes, a specific type of diode, can be used as voltage references and voltage regulators. Diodes are fundamental components in modern electronics, playing a vital role in controlling and directing the flow of electrical current.
