The specification of ESD protection for TPD4E001-Q1

I would like to confirm the specification of TPD4E001-Q1.

It has the specification exceed IEC61000-4-2.

I have a question.

Does TPD4E001-Q1 meet ISO10605 with 330pF and 2kohm?

I think the peak current is small but the energy is bigger than IEC610004-2.

So, I don't know wheter it meets or not.

Best regards,

  • Atsushi,

    They are definitely two different waveforms, with the ISO one being higher current for a longer time, so the voltage level rating of TPD4E001-Q1 will be different for each standard. There is not a good way to correlate the two standards, except to say that TPD4E001-Q1 probably can't pass +/- 8 kV in  ISO10605 since the voltage and current are so much higher for much longer.

    Here is a look at the voltage and current difference between the two specs based on the RC constants (they are not really what the waveform looks like, but gives us an idea what the difference between the two is)

    We can see that for an 8 kV ESD strike, the power in ISO exceeds IEC from about 100 ns and on. Also, the IEC event is done by about 200 ns, whereas the ISO event happens for longer than 1 us.

    What level of voltage are you trying to pass in ISO10605?

    Regards,
