How Does Zener Diode Work In Reverse Bias? A Zener diode is a silicon semiconductor device that permits current to flow in either a forward or reverse direction. … The Zener diode has a well-defined reverse-breakdown voltage, at which it starts conducting current, and continues operating continuously in the reverse-bias mode without getting damaged. Why
Why Is Zener Diode Reverse Biased? It acts as a normal diode in forwarding bias. When the Zener diode is reverse biased the junction potential increases. As the breakdown voltage is high this will provide high voltage handling capacity. As the reverse voltage is increased, the reverse current increases drastically at a certain reverse voltage.
What If Zener Diode Is Forward Biased? When forward biased voltage is applied to the zener diode, it works like a normal diode. … When reverse biased voltage applied to the zener diode reaches zener voltage, it starts allowing large amount of electric current. At this point, a small increase in reverse voltage will rapidly
Why Is The Reverse Bias Current Extremely Small? When a diode is reverse biased, the width of the depletion region increases. … Minority carriers of each material are pushed through the depletion zone to the junction. This action causes a very small leakage current to occur. Why is current in reverse bias small? Reverse leakage
