Human Body Model
Figure
8 shows the Human Body Model and
Figure
9
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 inter-
est, which is then discharged into the device through a
1.5k
resistor.
IEC 1000-4-2
Since January 1996, all equipment manufactured and/or
sold in the European community has been required to
meet the stringent IEC 1000-4-2 specification. The IEC
1000-4-2 standard covers ESD testing and performance
of finished equipment; it does not specifically refer to
integrated circuits. The MAX4838
–
MAX4841 help users
design equipment that meets Level 3 of IEC 1000-4-2,
without additional ESD-protection components.
The main difference between tests done using the
Human Body Model and IEC 1000-4-2 is higher peak
current in IEC 1000-4-2. Because series resistance is
lower in the IEC 1000-4-2 ESD test model (
Figure
10),
the ESD-withstand voltage measured to this standard is
generally lower than that measured using the Human
Body Model.
Figure
11 shows the current waveform for
the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge
test. The Air-Gap test involves approaching the device
with a charger probe. The Contact Discharge method
connects the probe to the device before the probe is
energized.
