8. Human body model: a 100 pF capacitor is discharged through a 1.5 kΩ resistor between two pins of the
device. This is done for all couples of pin combinations while other pins are floating.
9. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5
Ω).
This is done for all couples of
pin combinations while other pins are floating.
10. Charged device model: all pins and package are charged together to the specified voltage and then
discharged directly to ground.
