The following is taken from Application Note
AND8308/D − Interpretation of Datasheet Parameters
for ESD Devices.
ESD Voltage Clamping
voltage that an IC will be exposed to during an ESD event
to as low a voltage as possible. The ESD clamping voltage
is the voltage drop across the ESD protection diode during
an ESD event per the IEC61000−4−2 waveform. Since the
IEC61000−4−2 was written as a pass/fail spec for larger
IEC 61000−4−2 Spec.

systems such as cell phones or laptop computers it is not
clearly defined in the spec how to specify a clamping
voltage at the device level. ON Semiconductor has
developed a way to examine the entire voltage waveform
across the ESD protection diode over the time domain of
an ESD pulse in the form of an oscilloscope screenshot,
which can be found on the datasheets for all ESD protection
diodes. For more information on how ON Semiconductor
creates these screenshots and how to interpret them please
refer to AND8307/D.
