I believe you would not be far off to take the IEC waveform as the worst
case.
The amount of charge is pretty well approximated by the IEC ESD simulator.
The discharge waveform shape depends on the impedance of the source - the
person holding it, and the ESD trace on the circuit pack (and its
pack ESD drain

Hi David,
In general, I would have to know the geometry of the equipment to
answer the question. In general, voltage is not so important as
current and it can be in the several tens of amperes. And...current is
not so important as di/dt for upset effects on equipment. The result
is that low
