zener diode is a revers bias diode which used for voltage regulation.
A zener diode, in the reverse bias condition, presents a higher voltage. The current, however, is a function of the supplying circuit.
sharp reverse breakdown function
a zener regulator must sustain its own current to function plus the load currents IC regulator on the other hand will require very little current to sustain regulation plus there is a gain regulation that a zener do not have.
Clarence Zener is a physicist from the United States who is credited with the invention of the Zener diode. He studied subjects like superconductivity and diffusion.
zener diode is a special type of pn junction diode that work in breakdown region . There are two types of brekdowns in zener i.e avlanche breakdown and zener breakdown depending on the doping concentration. A zener diode in an on state can be considered as a voltage source ,equal to its zener voltage n hence act as an voltage regulator
The function of a zener diode is for it to act as a voltage regulator in the breakdown region.
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.

zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
A Zener barrier is an intrinsic safety equipment. It allows short circuiting of cables to each other or to metallic parts connected to ground without danger.
a zener regulator must sustain its own current to function plus the load currents IC regulator on the other hand will require very little current to sustain regulation plus there is a gain regulation that a zener do not have.
The dynamic resistance of a diode, be it zener or otherwise, will be different from its static resistance because a diode is not a resistor, and resistance is not a function of current flow. It is a diode, and a diode has its own characteristic voltage to current curve, forward and, in the case of a zener, reverse.
In the zener region of a diode, there is a relatively flat, low slope line for voltage as a function of current. As a result, increasing current in the zener region does not result in a significant increase in voltage - hence, voltage stability.
Zener diodes work by allowing current to flow in the reverse direction when a certain voltage, called the Zener voltage, is reached. Their function in electronic circuits is to regulate voltage by maintaining a constant voltage across their terminals, even when the input voltage changes. This helps protect sensitive components from voltage spikes and ensures stable operation of the circuit.
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
