Why Zener Diodes Don't Have Current Leakage

[ahjie]

Can someone help me ?
i can't understand why zener diode don't have current leakage?

 

[carlgrace]

It does. Every diode has some leakage.

My lecturer say it don't have leakage current in revere bias circuit ? (include in pratical)

 

[carlgrace]

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.
