A zener diode has a heavily doped p-n junction allowing electrons to tunnel from the valence band of the p-type material to the conduction band of the n-type material, such that the reverse voltage is "clamped" to a known value, called the zener voltage.
Applications of Zener Diodes are as follows:
1. Voltage Regulators (in shunt mode) ,
2. Surge Suppressors .i.e. for device protection
Zener diodes are used for voltage regulation
Your question makes no sense.
The primary use of a zener is to regulate voltage.
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
When the design says 4.9v zener diode that is all I would put. The more complicated an alternative you try the more things that can go wrong. A silicon diode is not the same as a zener diode, and cannot be used to replace a zener, with reasonable expectation that the circuit will continue to operate as designed.
The function of a zener diode is for it to act as a voltage regulator in the breakdown region.
No. The purpose of the zener diode is to clip (turn on) at a certain voltage. A capacitor will not exhibit this behavior.
Reverse bias
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
Zener diode is heavily doped pn junction diode.
No. A zener diode is a voltage limiter. Circuit design might create a current limiting response, but the basic control is voltage, not current.

A zener diode cannot be used as switch.
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
zener diode is a revers bias diode which used for voltage regulation.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
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.
Since they are in parallel, the 3.3V zener diode will "kick in" first when you reach 3.3V, and the circuit will pretty much act the same as if the 7V zener diode isn't there at all.
