“…To measure the discharge current a resistive load was used, as defined by the IEC [4]. This resistive load (Pellegrini target MD 101) [11] was designed to measure discharge currents by ESD events on the target area and its bandwidth is ranged from dc to above 1 GHz. The Pellegrini target was placed on a horizontal metal plane with dimensions 1.5 · 1.5 m 2 , which was placed 70 cm above the ground.…”

The electrostatic discharge (ESD) between charged metal objects produces electromagnetic (EM) fields having broad-band frequency spectra over a microwave region, which cause serious EM interference (EMI) to high-tech information equipment. For this kind of ESD fields, focussing on EM fields due to the spark discharge between metal spheres in free space, we previously demonstrated that the presence of metal spheres enhances the field level according to their sizes. For the EMI due to the above ESD, however, its mechanism is not still elucidated. This may be because even the fundamental propagation characteristics of ESD fields above a ground plane or inside a room remains unknown in conjunction with the EM coupling to equipment. In this paper, we analyzed the electric field due to an ESD event occurring in a corridor using the current dipole inside a rectangular waveguide. The distance attenuation of the field peak for the ESD occuring horizontally to the floor was examined numerically. As a result, we found that the far-field peak dopes not always decrease with increasing the distance and that there exists a region in which the field peak is enhanced with the distance. This finding was also confirmed by the spark experiment of metal spheres inside a corridor.

“…They found that there exists a specific relationship of between the current peak I p and the rise time t r regardless of approaching speed of the gun [5]. However, the transfer impedance of the Pellegrini target has been shown to be dependent [6,7] on the frequency, and so the specific relationship above is affected by the frequency characteristics of the Pellegrini target.…”

SUMMARYAn immunity testing method for electrostatic discharge (ESD) is being specified in IEC 61000-4-2, in which the contact discharge of an ESD gun is being normally specified. Air discharge testing is known to be a severe immunity test compared to contact discharge testing, while the discharge current injected is not well reproduced. Grasping the behavior of the current injected by the air discharge would be helpful in establishing the worst-case ESD immunity testing. We previously measured the discharge currents for air discharge testing onto the IEC-recommended current transducer with a commercially available ESD gun, and showed that there exists a specific relationship of I p ⋅ t r ξ / V c = constant (ξ = 0.75), between rise time t r and current peak I p . The current transducer, however, has a frequency-dependent transfer impedance which should affect the measured current waveform. In this study, we investigated whether the above-mentioned specific relationship can be obtained for air discharge of an ESD gun onto a ground that assumes a metal enclosure of electronic equipment under test. A method was presented for estimating the discharge current from simultaneously measured magnetic fields with two magnetic field probes regardless of the distance between the gun discharge-point and the probe position. This method was validated for contact discharge of an ESD gun to an SMA connector. With this method, we estimated the discharge currents injected onto a ground for air discharge testing of an ESD gun with intentionally fast and slow approaches. As a result, we could confirm a specific relationship between rise time t r and current peak I p of I p ⋅ t r ξ / V c = constant with ξ = 0.57 independent of charge voltages and gun approaches.
