I need to find the theta Jc for MC33179DR2G.

Psi J-Case-top ~ 30°C/W The best we can do in this situation is to use Psi J-Case-top to characterize the application. Power up the circuit wait for 10 minutes then make a case temperature measurement. Then calculate the junction temperature. Tj=Tcase + Psi J-Case-top*Pd Thank you. Answered by:
