Zener Diode

A Zener diode is a special type of diode designed to allow current to flow in the reverse direction when a specific voltage, called the Zener voltage, is reached. Unlike regular diodes that block reverse current, Zener diodes are used to regulate voltage within electronic circuits. When the voltage across the diode hits this threshold, it conducts in reverse, maintaining a steady voltage level and protecting other components from voltage spikes. They are commonly used in power supplies and voltage regulation applications to ensure consistent performance.
