LA47510
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)
