Note : Power consumption (Pd), junction-to-case thermal resistance (
θj-c), heat sink thermal resistance (θf), junction
temperature (Tj), case temperature (Tc), and ambient temperature (Ta) have the relationship shown in the
following equation.
Tj = Pd (
θj-c+θf) +Ta
= Pd
×θj-c+Tc,
*Tc = Pd
×θf+Ta However, Tj max is limited by Tstg max (150°C).
