Appendix A Electrical Characteristics
PD = K ÷ (TJ + 273°C)
Solving Equation A-1 and Equation A-2 for K gives:
Eqn. A-2
K = PD à (TA + 273°C) + θJA à (PD)2
Eqn. A-3
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 A-1 and Equation A-2 iteratively for any value of TA.
