    Can someone help me ?
    i cant understand why zener diode dont have curent leakage?

    It does. Every diode has some leakage.

    My lecturer say it dont have leakage current in revere bias circuit ? (include in pratical)

    Your lecturer is wrong. All diodes have leakage current. It is their nature.

    Here is the first zener diode datasheet I found on Google.


    Check out the Electrical Characteristics.... it lists the maximum reverse current.

    I suppose it depends on how you look at it. It won't have leakage when in reverse breakdown since it is conducting and is supposed to be conducting. I would agree with carlgrace in that the lecturer has some wires crossed.
