Zener Diode is nothing but a Crystal P-n junction diode in which the P type and n-type layers are heavily doped.Zener diode is mainly used as voltage regulator
its forward charaqcteristic is same as normal p-n junsction diode but its reverse Characteristic is different that when the reverse region reaches knee region in spite of changes in current the voltage remains the same
zener diode is a revers bias diode which used for voltage regulation.
to limit the voltage or regulate the same.
Reverse Bias
A zener diode has a relatively flat voltage to current curve when reverse biased. Within limits, you can consider that the voltage across the zener diode is constant. You can use the zener as the primary regulator, so long as you consider the power requirements and dissipation of both the zener and the load, and you do not overload the zener. More often, the zener is used as a voltage reference in a larger power supply that uses other components, linear or switched, to supply the load.
3.2
A zener diode cannot be used as switch.
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
zener diode is a revers bias diode which used for voltage regulation.
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.
Yes **************************************** Yes they can but there are pitfalls. A normal diode will have a high reverse breakdown voltage. A zener has a relatively low breakdown voltage (its "zener"voltage). If a zener diode is used as a rectifier it must have a zener voltage at least twice the peak of the applied a.c.
Zener diode is heavily doped pn junction diode.

No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.

Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
