ESD122: Leakage Specifications

Part Number: ESD122

Hi,

I would like to know more about the leakage of the ESD122.

First, it looks like the typical leakage is much lower, around 0.6 nA worst case on on Figure 8.  Where does the 10nA of leakage situation come from?

Also, is there a worst case mismatch of leakage current between the two channels?

  • Hello,
    The maximum leakage is a guaranteed value over temperature and process.
    For this device there should be extremely minimal leakage between channels. This value is not guaranteed by the data sheet but I could try and find a typical value if you want it.
    Regards,

  • Sorry, I should clarify my question a bit. Would the leakage of IO1 to GND be much different from IO2 to GND? Assuming they are at the same voltage.
  • In reply to Christopher Meehan:

    No the leakage should not be much different channel to channel at the same voltage.

    Do you have any data that could quantify what this would be worst case?

    Thanks!

    Hi Christopher,

    We measured ILeak on 8 units at room temp and the worst case delta observed between IO1 and IO2 was 20pA.

    Thanks,

    Moe
