Characteristics of contact discharge using 6GHz current probe
New shield-type current-probe was compared to a conventional type current-probe by measuring frequency response and TLP pulse. The shield type current-probe, which provided low distortion and 6GHz BW, approximated the input waveform. The contact discharge was investigated using 4pF to 20pF capacitances. The current waveforms discharging from the 4pF reached the peak value at the leading edge and decayed rapidly. The current waveforms discharging from the 20pF rose up slowly and reached the peak value after the leading edge. The peak current discharging from the 4pF or 20pF increased almost proportionally from 40mA at 10V to over 300mA at 70V. At the 4pF capacitance the rise time tended to increase from 50ps to 150ps as the voltage decreased from 70V to 10V. The shield-type current-probe was useful for measuring the contact discharge.
