Hi
I'm Jacob Johnson. I want to design a board in which MOSFETs are used as switching devices. In this design I want to calculate the PCB temperature while FETs are dissipating Pdis watts. So I need the thermal resistance of the FET case to ambient, but there is no simple equation for this value. Now I want to ask you a document or reference about this matter that explains how to calculate case to ambient thermal resistance.
Regards
Jacob
