APPLICATION INFORMATION
Figure 8. Typical HBM Current Waveform
IEC61000-4-2 (Formerly Known as IEC1000-4-2)
Unlike the HBM, MM, and CDM ESD tests that apply to component level integrated circuits, the IEC61000-4-2 is
a system-level ESD testing and performance standard that pertains to the end equipment. The MAX3243E is
designed to enable the manufacturer in meeting the highest level (Level 4) of IEC61000-4-2 ESD protection with
no further need of external ESD protection circuitry. The more stringent IEC test standard has a higher peak
current than the HBM, due to the lower series resistance in the IEC model.
Figure 9 shows the IEC61000-4-2 model, and Figure 10 shows the current waveform for the corresponding
±8-kV Contact-Discharge (Level 4) test. This waveform is applied to a probe that has been connected to the
DUT. On the other hand, the corresponding ±15-kV (Level 4) Air-Gap Discharge test involves approaching the
DUT with an already energized probe.
