Zener diode

  1. Can someone help me ?
    i cant understand why zener diode dont have curent leakage?
  2. jcsd
  3. It does. Every diode has some leakage.
  4. My lecturer say it dont have leakage current in revere bias circuit ? (include in pratical)
  5. 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.
  6. 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.
