PD = K ÷ (TJ + 273°C)
Eqn. A-2
Solving Equation A-1 and Equation A-2 for K gives:
K = PD × (TA + 273°C) + θJA × (PD)
2
Eqn. A-3
where K is a constant pertaining to the particular part. K can be determined from Equation A-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 equations 1 and 2 iteratively for any value of TA.

Electrostatic Discharge (ESD) Protection Characteristics
Although damage from static discharge is much less common on these devices than on early CMOS
circuits, normal handling precautions should be used to avoid exposure to static discharge. Qualification
tests are performed to ensure that these devices can withstand exposure to reasonable levels of static
without suffering any permanent damage. All ESD testing is in conformity with CDF-AEC-Q00 Stress
Test Qualification for Automotive Grade Integrated Circuits. (http://www.aecouncil.com/) A device is
considered to have failed if, after exposure to ESD pulses, the device no longer meets the device
specification requirements. Complete dc parametric and functional testing is performed per the applicable
device specification at room temperature followed by hot temperature, unless specified otherwise in the
device specification.
