要約(英語): Immunity testing for human electrostatic discharges (ESDs) is prescribed in IEC 61000-4-2, in which an ESD generator or ESD gun is used to inject into equipment under test the discharge current through a lumped resistor from a charged lumped capacitor. In actual ESD events from a charged human, however, charges distributed on the body surface should be discharged through a spark from his/her fingertip, and therefore its situation can essentially be different from that of the ESD gun. To grasp the behavior of the discharge currents for human ESDs, using a 12 GHz digital oscilloscope we measured discharge currents caused by air discharges through the fingertip or hand-held metal bar from a charged human with respect to charge voltages from 300 V to 3 kV. Results show that at charge voltages of less than 1 kV, the fingertip contact causes discharge bursts, whose occurrence frequencies increase with decreasing the charge voltages, while the hand-held metal bar at any charge voltages makes discharges complete at a time.
