Junction temperature

Steady-state thermal stack. Uses extracted Rth(j-c) and Rth(j-a).

PartTotal dissipation P_loss (W)Ambient temperature T_amb (°C)Rth case-to-sink (°C/W)Rth sink-to-ambient (°C/W)

Tj = T_amb + P · (R_jc + R_cs + R_sa)

Rth(j-c) (extracted)1 °C/W

Rth(j-a) (inferred)40 °C/W

Case temperature56 °C

Junction temperature (with heatsink)76 °C

Junction temperature (no heatsink, R_ja only)840 °C

Steady-state model. For pulsed loads use the transient Zth(j-c) curve on the component's Thermal tab.
