6.2 Characteristics
Figure 2: P331-2 pulse form
Figure 3: P331-2 equivalent circuit diagram
The ESD pulse is characterized by its current characteristic which is shown in
shows the equivalent circuit diagram of the P331-2 probe. Both are in accordance with
the standard IEC 64000-4-2. Please refer to
for the respective waveform parameters.

K where: K = 3.7 A / kV
The equation reveals that the probe supplies 3.7 A per kV of the generator voltage.
Note:
The pulse form is only guaranteed if the P331-2 probe is operated at a
minimum voltage of
200 Volt
.
