ESD performance depends on a variety of conditions.

test setup, test methodology, and test results.
Figure 10a shows the Human Body Model, and Figure
10b shows the current waveform it generates when dis-
charged 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
1.5kΩ resistor.
The IEC 61000-4-2 standard covers ESD testing and
performance of finished equipment. However, it does

not specifically refer to integrated circuits. The
MAX13430E family of devices helps you design equip-
ment to meet IEC 61000-4-2, without the need for addi-
tional ESD-protection components.
The major 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 model. Hence, the ESD with-
stand voltage measured to IEC 61000-4-2 is generally
lower than that measured using the Human Body
Model. Figure 10c shows the IEC 61000-4-2 model, and
Figure 10d shows the current waveform for IEC 61000-
4-2 ESD Contact Discharge test.
