Working Principle

A Zener diode works on a principle known as avalanche breakdown. In this process, an electric current passes through the diode, causing the voltage across it to rise. When the voltage across the diode reaches a certain level, known as the Zener voltage, the diode begins to conduct in the reverse direction. This allows for precise voltage regulation and can be used to ensure operation at a given voltage. Additionally, Zener diodes are well suited for use in actions such as overvoltage protection, where they limit the amount of current passing through the system to a safe level.
