CURRENT WAVEFORM
Figure 6b. Human Body Current Waveform
ESD protection can be tested in various ways;
these products are characterized for protection to the
following limits:
1) ±15kV using the Human Body Model
2) ±8kV using the Contact-Discharge method specified
in IEC 1000-4-2
3) ±15kV using IEC 1000-4-2’s Air-Gap method.
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents test
setup, test methodology, and test results.

discharged into a low impedance. This model consists
of a 100pF capacitor charged to the ESD voltage of
interest, which is then discharged into the test device
through a 1.5kresistor.
IEC 1000-4-2
The IEC 1000-4-2 standard covers ESD testing and
performance of finished equipment; it does not
specifically refer to integrated circuits. The MAX6816–
MAX6818 help you design equipment that meets
Level 4 (the highest level) of IEC 1000-4-2,
without the need for additional ESD-protection
components.
