Manufacturers and engineering communities follow the standards published by International Electrotechnical Commission (IEC) when referring to the robustness of protection devices. Comchip ESD products are designed to meet industry immunity standards such as IEC-61000-4-2, the electrostatic discharge immunity test, which specifies 8kV contact discharge and 15kV air discharge. This slide shows the ESD input waveform defined by IEC-61000-4-2.
