[1] Junction temperature in accordance with “IEC 60747-1”. An alternative definition is: Tvj = Tamb + P × Rth(vj-a)
where Rth(vj-a) is a fixed value to be used for the calculation of Tvj. The rating for Tvj limits the allowable
combinations of power dissipation (P) and operating ambient temperature (Tamb).
