Relationship between breakdown field and radiated electromagnetic field strength due to low voltage ESD below 1kV

Relationship between breakdown field strength and radiated electromagnetic field strength was examined in experimental study. In the first, transition duration of voltage and current rise time due to small gap discharge as the low voltage ESD investigated in time domain. The measurement system used the 12 GHz experimental system. And so, the sensing system was used an E-field sensor and a H-field sensor. As a consequence of the experiment using the system, voltage and current rise time of transition duration were shown 32 ps or less. Besides, breakdown field was examined to corroborate the very fast transition durations of about 32 ps. The breakdown field was very high of about 8 times 10⁷ V/m in low voltage discharging of below 350 V. Also we confirmed that the radiated electromagnetic field strength value in low voltage discharge of about 400 V was higher than high voltage discharge of about 900 V.
