When looking at a voltage waveform of an ESD protection device exposed to the IEC61000-4-2 there will typically be an initial voltage spike followed by a secondary peak and eventually the voltage will level off.his article will explain the key steps involved in selecting effective ESD protection. ESD waveform. The most commonly used waveform for defining a typical ESD event at the system level is the IEC61000-4-2 waveform which is distinguished by its sub nanosecond rise time and high current levels (see Figure 1).
