**A Zener diode is a special type of diode designed to operate in the reverse-biased direction. *Unlike regular diodes that break down under reverse voltage, Zener diodes are engineered to have a controlled breakdown at a specified voltage, known as the Zener voltage (Vz). When a Zener diode, is reverse-biased and the voltage across its terminals exceeds the Zener voltage, it starts conducting in the reverse direction. This controlled breakdown allows the Zener diode to regulate voltage effectively. "Zener diodes are commonly used in voltage regulation circuits. By placing a Zener diode in parallel with the load, it ensures that the voltage across the load remains relatively constant, even if there are variations in the input voltage.
