IEC 61000-4-2

The IEC 61000-4-2 standard covers ESD testing and performance of finished equipment. It does not specifically refer to

integrated circuits. The MAX20340 is specified for ±3kV Air-Gap and ±10kV Contact Discharge IEC 61000-4-2 on the

PLC pin.

The main difference between tests done using the Human Body Model and IEC 61000-4-2 is higher peak current in IEC

61000-4-2. Because series resistance is lower in the IEC 61000-4-2 ESD test model (Figure 14), the ESD-withstand

voltage measured to this standard is generally lower than that measured using the Human Body Model. Figure 15 shows

the current waveform for the ±6kV IEC 61000-4-2 Level 4 ESD Contact Discharge test. The Contact Discharge method

connects the probe to the device before the probe is energized.
