A Zener diode is a type of semiconductor diode that is designed to operate in the reverse-bias mode.
Unlike a conventional diode, which acts as a one-way valve for electrical current, a Zener diode is designed to allow current to flow in the reverse direction when a specific, predetermined voltage, called the Zener voltage, is reached.
In other words, when the voltage across the Zener diode reaches the Zener voltage, the diode begins to conduct in the reverse direction, allowing current to flow from the cathode to the anode.
This reverse current helps to regulate the voltage across the diode, ensuring that it remains at a constant value, the Zener voltage, regardless of changes in the current flowing through the diode.
Zener diodes are commonly used in voltage regulator circuits, where they are used to maintain a constant voltage level in the presence of varying input voltage and load conditions.
They are also used in applications such as overvoltage protection, voltage references, and power supply clipping circuits.
Zener diodes are designed to operate in the reverse-bias mode and are not suitable for use in the forward-bias mode, as this can cause the diode to break down and become damaged.
