A: If you have a ramp generator or make one LM555 then feed it to the zener don' t forget the limiting resistor with the scope across the zener the display will dhow its voltage and current characteristics. you can do the same for a diode even a transistor and more.
zener diode
SILICON same as any other diode but with different characteristics
A Zener Diode will continue to show its breakdown characteristics until it gets fried...for example a 5 volt zener will get fried at a breakdown voltage of about 6 volts..this happens because of the large amount of current flowing through the small diode which unfortunately the diode cannot handle.
zener diode is a revers bias diode which used for voltage regulation.
to limit the voltage or regulate the same.
The Zener diode has the characteristics of a constant voltage source.
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
what is the difference between reverse characteristics of zener diode and a practical diode ?
zener 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.
SILICON same as any other diode but with different characteristics
Zener diode is heavily doped pn junction diode.

Work in reverse bias.(breakdown at a particular voltage to keep the volt. constant so used as voltage regulator) same as diode when forward biased.
A zener diode cannot be used as switch.
Dr. Clarence Melvin Zener of Southern Illinois University invented the zener diode.
