ESD - WAVE-FORM CALCULATION, FIELD AND CURRENT OF HUMAN AND SIMULATORESD

Currents, current derivatives and transient fields of human ESDs are c ompared to currents and fields caused by commercial simulators. The re sults point at undefined but influential parameters of simulators and the standardized setup used. Suggestions for possible improvements of ESD test standards are given. A calculation method for the ESD current is provided. This method includes an are model. Possible high peak cu rrent values (> 10 A/kV) are validated by a simple physical model of t he hand-metal piece geometry. By calculation it is shown under which c ircumstances human ESD currents come close to the standardized wavefor m of simulators.
