the ESD that withstands voltage measured to IEC 1000-
4-2 is generally lower than that measured using the
Human Body Model. Figure 6a shows the IEEE 1000-4-
2 model and Figure 6b shows the current waveform for
the ±8kV IEC 1000-4-2 Level 4 ESD Contact-Discharge
test.
The Air-Gap Method involves approaching the device
with a charged probe. The Contact-Discharge Method
connects the probe to the device before the probe is
energized.
Machine Model
The Machine Model for ESD tests all pins, using a
200pF storage capacitor and zero discharge resis-
tance. Its objective is to emulate the stress caused not
only by RS-232 inputs and outputs, but also by contact
that occurs due to handling and assembling during
manufacturing. Therefore, after PC board assembly, the
Machine Model is less relevant to I/O ports.
