A diode (some people incorrectly call them rectifiers) is a semiconductor device that allows a current to flow in one direction. A Zener diode allows a reverse to current to flow at a defined voltage. A common application for them is as a voltage regulator. Named for C M Zener , US Physicist. A zener diode is a diode and like all diodes it will conduct in both directions. If a reversed voltage is applied it will breakdown and conduct current. Most diodes when they breakdown the reversed voltage cannot be predictable. However a zener diode when they do breakdown in the reverse voltage mode that voltage can be made as predictable and remain +/- % of the breakdown voltage. Therefore this steady voltage can be used as a regulator for instance or a definite voltage drop if need be.
The determination of whether a zener shunt regulator is better than a zener series regulator depends on the specific design requirements of the circuit. Each approach has its pros and cons. Primary consideration would be for power dissipation and load rejection ratios.
A: Once a zener breakdown in the reverse diode direction.That becomes the region of operation
A: A ZENER can be used as a series regulator to limit the voltage available to the next circuit in line.

The breakdown voltage point for a Zener diode is 17 volts
Zener breakdown is the phenomena wherein the Zener diode experiences reverse breakdown at a much lower voltage than a normal diode, which may breakdown in excess of 100 volts, depending on the type. This is useful because the Zener will hold the same voltage after breakdown, regardless of the input voltage, making them excellent for voltage controlled switches and references.
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
A zener diode has a relatively constant reverse voltage, at the designated zener voltage. If you had a circuit, say, with an AC source, a resistor, and a zener, the waveform across the zener would be the AC source, clipped at the reverse bias zener voltage, and clipped again at the forward bias voltage, typically about 0.7 V.
The breakdown voltage point for a Zener diode is 17 volts
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
A zener diode passes drect current, and the point of a zener diode is that the voltage across it stays nearly constant over a range of different currents, so it can provide a supply of stabilised voltage.
