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.
Yes. The intended use of a zener diode is to be reverse biased at the breakdown voltage. In this mode, the zener has high slope in the current to voltage curve, making it a good choice for voltage regulation.
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.
to limit the voltage or regulate the same.

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.
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.
