- A Zener diode is a heavily doped semiconductor device that is designed to operate in the reverse direction.
- Under the forward-bias condition, the zener diode works as a normal PN junction diode.
- During the reverse-bias condition, when the voltage across the terminals of a zener diode reaches the zener Voltage (breakdown voltage), the junction breaks down, and the current flows from the cathode to the anode.
- The primary characteristic that distinguishes a Zener diode from a regular diode is its ability to maintain a constant voltage in the reverse breakdown region.
- This is due to the Zener diode's designed doping, allowing it to conduct current when the reverse voltage reaches a specific value, known as the Zener voltage. This feature makes Zener diodes useful for voltage regulation and protection.
