3.6 Electrostatic discharge (ESD) characteristics
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are applied to the pins of each sample according
to each pin combination. The sample size depends on the number of supply pins in the device (3 parts × (n + 1) supply pin).
This test conforms to the AEC-Q100-002/-003/-011 standard.
