ESD: Waveform Calculation, Field and Current of Human and Simulator ESD

Currents, current derivatives and transient fields of human ESDs are compared to currents and fields caused by commercial simulators. The results 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 arc model. Possible high peak current values (\u3e 10 A/kV) are validated by a simple physical model of the hand-metal piece geometry. By calculation it is shown under which circumstances human ESD currents come close to the standardized waveform of simulators
