Zener Diode - Symbol, Construction, Working and Applications
What is a Zener Diode? A Zener diode is a type of PN junction diode that is designed to conduct in both forward and reverse directions. It has heavily doped regions and is mainly used to conduct current in the reverse direction. It starts conducting in the reverse direction when the reverse voltage exceeds a certain limit known as the reverse breakdown or Zener breakdown voltage.
Zener Diode - Definition, Working, Circuit Symbol, V-I
From the diagram, we can see that the band around the package corresponds to the line on the diode circuit symbol and this can be an easy way of remembering which end is for which. The Zener diode circuit symbol places two tags at the end of the bar – one in the upward direction and the other in the lower direction, as shown in the figure.

Zener Diode as a Voltage Regulator: Working and Principles
Jul 12, 2022Zener Diode as a Voltage Regulator helps to regulate the voltage across small loads. Zener Diode acts as a voltage regulator when it is given reverse bias feedback and a small leakage current is generated until a constant voltage is obtained. There is a typical flow of current from anode to cathode in a Zener diode. When loaded in the forward direction, the Zener
