8.2 Peak clamping voltage

The peak clamping voltage for forward and reverse current pulses of 8/20

µs

(IEC 61000-4-5) is significant when protecting circuits from power surges due to voltage

discharges. The current pulse shape over time is shown in Figure 9. The basic

measurement setup for forward current and reverse current pulses respectively are shown

in Figure 8 and Figure 14.
