I understand that, and probably they use this approach for getting a lower Rth value compared to other competitors.
I have already used some FEM simulation tools as ANSYS for this purspose however I would like to develope a method for estimating Rth Junction-Top Case only by using datasheet...
Good morning everybody.
I am working on the estimation of Rth junction-TopCase for power transistors. For this purpose, I need the thermal information provided by the manufacturer. I mainly work with Infineon who always gives the same comment in their datasheets:
"Device on 40 mm x 40 mm x 1.5...
