The Zener diode is a semiconductor device that allows current to flow in both directions and it is a heavily doped p.n junction diode it is commonly used in voltage regulation circuits due to its ability to maintain a constant voltage.
Symbol of Zener diode
The symbol of the diode mostly works on the reverse bias and Zener diode to the regular diode but including the bent arrow pointing out of the cathode the Zener diode its ability to conduct in reverse bias
working principle of Zener diode
This diode is highly doped with impurities of the diode making the conductive and easily conducting electricity compared with the other p-n junction diode all impurities reduce the depletion layer of this diode and also make it very lanky. this diode works if the applied is very small
In no biasing, the conduction of the Zener diode of all electronic step-by-step in the valance band of a p-type semiconductor device and no current flowing occur through the diode
Working principle of Zener diode of reverse biased
In the forward biased the Zener diode works like the powerful diode but the reverse biased condition of some leakage of the current flow through the diode. The Zener diode minimum breaks the voltage causing some parts of the insulation to experience electricity conditions in this voltage range of 2.3V to 202 and that can go up to 1kv
