where K is a constant pertaining to the particular part. K can be determined from Equation 3 by measuring PD (at equilibrium)
for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving Equation 1 and Equation 2 iteratively
for any value of TA.

1 All ESD testing is in conformity with CDF-AEC-Q100 Stress Test Qualification for
Automotive Grade Integrated Circuits.
2 A device is defined as a failure if after exposure to ESD pulses the device no longer meets
the device specification requirements. Complete DC parametric and functional testing is
performed per applicable device specification at room temperature followed by hot
temperature, unless specified otherwise in the device specification.
