Definition Zener Diode

The Zener diode is a highly versatile semiconductor device that finds extensive use in various electronic circuits. Designed with a unique property called the Zener breakdown, this diode can operate in reverse bias without getting damaged due to excessive voltage. With its ability to regulate voltage and protect sensitive components, the Zener diode is widely used as a voltage reference or shunt regulator. This capability makes it useful in applications such as power supplies, voltage regulators, and surge protectors. The Zener diode is carefully manufactured to provide a specific voltage rating, ranging from a few volts to a few hundred volts. This wide range of voltage options allows engineers to select the most suitable diode for their specific circuit requirements. In addition to voltage regulation, the Zener diode also exhibits low resistance in the forward direction, making it an ideal component for specific applications like voltage clamping or clipping. Its compact size and high reliability make it a popular choice among electronic designers. Overall, the Zener diode is an indispensable component in modern electronic circuits due to its ability to control and regulate voltage, ensuring stable and reliable operation.
