Research Abstract	Regarding to grasping characteristics of discharge currents for air discharges of an ESD-gun with low charge voltages, it is found that the fastest rise time of discharge current waveforms for several hundred volts is 15 ps. An equivalent circuit modeling for air discharges of ESD-guns to predict discharge current waveforms using spark-resistance formulae is proposed. It is found that the calculated discharge current waveforms derived from both spark resistance formulae approximately agree with the measured ones, and that Rompe-Weuzel's and Toepler's formulae can better predict their rising slopes and tails, respectively. Our future task is to grasp characteristics of discharge currents for low charge voltages of an ESD-gun injected onto real communication equipment, such as discharge currents and breakdown fields.
