Note) The relationship between the power dissipation (Pd) and the junction-to-case thermal resistance (
θj-c), heat sink
thermal resistance (
θf) and junction temperature (Tj), case temperature (Tc), and ambient temperature (Ta) is as
expressed by the following equation :
Tj = Pd (
θj-c+θf) +Ta
= Pd
×θj-c+Tc,
*Tc = Pd
×θf+Ta
Note that Tj max must be limited with Tstg max (150
°C).
