IEC 1000-4-2
Since January 1996, all equipment manufactured
and/or sold in the European Union has been required to
meet the stringent IEC 1000-4-2 specification. The IEC
1000-4-2 standard covers ESD testing and perfor-
mance of finished equipment. It does not specifically
refer to ICs. The MAX4864L/MAX4865L/MAX4866L/
MAX4867 help users design equipment that meets
Level 3 of IEC 1000-4-2, without additional ESD-protec-
tion components.
The main 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 ESD test model (Figure 9), the
ESD-withstand voltage measured to this standard is gen-
erally lower than that measured using the Human Body
Model. Figure 10 shows the current waveform for the
±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.
The Air-Gap test involves approaching the device with a
charger probe. The Contact Discharge method connects
the probe to the device before the probe is energized.
