IEC 1000-4-2

The IEC 1000-4-2 standard covers ESD testing and

performance of finished equipment; it does not specifi-

cally refer to integrated circuits (Figure 4).

The major difference between tests done using the

Human Body Model and IEC 1000-4-2 is higher peak

current in IEC 1000-4-2, because series resistance is

lower in the IEC 1000-4-2 model. Hence, the ESD with-

stand voltage measured to IEC 1000-4-2 is generally

lower than that measured using the Human Body Model.

Figure 5 shows the current waveform for the ±8kV IEC

1000-4-2 ESD Contact-Discharge test. The Air-Gap test

involves approaching the device with a charged probe.

The Contact-Discharge method connects the probe to

the device before the probe is energized.
