Abstract

Currents, current derivatives and transient fields of ESDs of humans are compared to currents and fields caused by simulators. A method for the simulation of the discharge current is provided. This method includes an arc model. The resulting high peak current values (>10 A/kV) are validated by a simple physical model of the hand geometry. Investigations of transient fields from simulators point to differences between simulators from different manufactures and between the transient fields caused by humans compared to the fields from simulators. Suggestions for possible improvements of the ESD test standard are given.
