Draw the characteristics curve of zener diode?

Question: Draw the characteristics curve of zener diode?

Zener diode is a semiconductor diode and it consists both p type and n type section with heavily doped so it consists large number of impurities in it and the result of heavily doped is low reverse breakdown voltage it is also controlled during the manufacturing of zener diode

Symbols:(Vz) zener voltage(reverse breakdown voltage known as zener voltage) 

:(Iz) Zener current(reverse current after the breakdown known as zener current)
