Maximum leakage current

Definition.

The Maximum Leakage Current parameter is used to set the maximum peak leakage current allowed by the digital isolator or optocoupler chip under test in uA. This setting should include both leakage and residual leakage (capacitive) at the test point, which is usually adjusted to a small enough value to be negligible. When the peak leakage current of the DUT is higher than the maximum setting, the [FAIL LEAK] flag on the test software will be triggered to prompt the user.

together withMinimum leakage currentThe difference is that the maximum leakage current detects the upper limit of leakage current.

Relevant testing instruments:

The maximum leakage voltage is determined by using the HT9464  Parameters to be set when testing the isolation voltage of an optocoupler or digital isolator chip.
