Overvoltage Protection Comparison
dv/dt Chart
Figure 5.3 shows a peak voltage comparison between SIDACtor devices, gas discharge
tubes, MOVs, and TVS diodes, all with a nominal stand-off voltage rating of 230 V. The
X axis represents the dv/dt (rise in voltage with respect to time) applied to each protector,
and the Y axis represents the maximum voltage drop across each protector.
