Figure 1d. IEC 61000-4-2 ESD Generator Current Waveform
Human Body Model (HBM)
Figure 1a shows the Human Body Model, and Figure
1b 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
that is then discharged into the test device through a
1.5kΩ resistor.
IEC 61000-4-2
The IEC 61000-4-2 standard covers ESD testing and
performance of finished equipment. However, it does
not specifically refer to integrated circuits. The
MAX4895E assists in designing equipment to meet IEC
61000-4-2 without the need for additional ESD-protec-
tion 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 1c shows the IEC 61000-4-2 model, and Figure
1d shows the current waveform for IEC 61000-4-2 ESD
Contact Discharge test.
