Describe Zener Diode

The Zener Diode is a specialized type of semiconductor diode that is designed to operate in the reverse breakdown region. It is primarily used for voltage regulation or voltage reference applications in electronic circuits. The key feature of a Zener diode is its ability to maintain a constant voltage across its terminals (known as the Zener voltage) even when the current is varied. This makes it ideal for protecting sensitive electronic components by limiting the voltage that they are exposed to. The Zener diode is commonly used in power supplies, voltage regulators, and overvoltage protection circuits. It provides stability and reliability in applications where precise voltage regulation is crucial. With its small size and low power dissipation, the Zener diode offers excellent performance in a wide range of applications. It is available in various voltage ratings, allowing designers to choose the optimal device for their specific requirements. Overall, the Zener diode is an important component in electronic circuits, ensuring stable voltage levels and protecting sensitive components from voltage spikes.
