Hi friend...!!
Zener diode defined as diode that allows current to flow in reverse direction.
Zener diode is highly doped p-n junction. Normal diode will also break down with reverse voltage but voltage & sharpness of knee are not as well defined as zener diode. Also normal diode are not designed to operate breakdown region but zener diode can reliably operate in this region.
Use of zener diode widely used in electronic equipment & one of the basic building blocks of electronic circuits. They are used to generate low power stabilized supply rails from higher voltage & to provide reference voltage for circuits,especially stabilized power supply.They are also used to protect circuits from overvoltage,especially electrostatic discharge.
I hope it help you...
