Answer Posted / srikrishna
zener diode is used as a voltage regulatory device..
because..
the voltage across the zener diode in reverse bias is
constant after reaching certain value i.e. breakdown
voltage.
normal diodes distorts at htis breakdown voltage but the
zener still runs after this voltage and keeps the voltage
across the diode constant even the supply voltage increses..
