What is zener diode and for what it is used?
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
What type of biasing must be used when a zener diode is used as a regulator?

What is the zener point?
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.
What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
Which diode used for signal amplification zener or schottky or tunnel or none?
The diode that has a negative resistance region in its voltage-current curve.
Is it pn junction diode used as voltage regulator?
zener diode
Can zener diode be used as fan regulaters?
A: NOT VERY WELL a zener requires to support booths its breakdown current and the fan current essentially the zener is a voltage regulator not a current regulator

What is the difference between p n junction and zener diode?
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.

Does a zener diode acts as a switch?
A zener diode cannot be used as switch.

The diode that has a negative resistance region in its voltage-current curve.
What is Zener diode function?
Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, aZener diode conducts when the voltage reaches the diode's reverse breakdown voltage.
When current through a zener diode increases by a factor of 2 by what factor does the voltage across the zener diode increase?
If the zener diode is in zener breakdown the voltage across the zener diode remains constant regardless of current (for the ideal zener diode). Real zener diodes have parasitic resistance that causes the voltage across the zener diode to increase slightly with increased current, but due to temperature dependant variations in this parasitic resistance as well as temperature dependant variations in the zener breakdown voltage, this change in voltage in real zener diodes cannot be described by a simple linear factor.
Discussion of zener diode a voltage regulation?
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.
