Abstract(in Japanese) (See Japanese page)
Abstract(in English) An immunity testing method for electrostatic discharge (ESD) is being specified in IEC61000-4-2, which normally recommends the contact discharge of an ESD-gun. Air discharge testing is known to be a severe immunity test compared to the contact discharge testing, while the discharge current injected is not well reproduced. We previously proposed an equivalent circuit model in order to predict the current waveform injected in contact discharge with an ESD-gun. In the present study, we show that the air discharge produces the discharge current waveform significantly affected by the approaching speed of an ESD-gun with the same charged voltage, and that the previously proposed equivalent circuit model is applicable to air discharge in view of the initial charges accumulated in the stray capacitance of the gun tip electrode and a constant spark resistance.
