Where can I find the thermal resistance network model parameters of the device in the PSIM thermal model, I did not find the corresponding values in the data sheet of the device. And how to solve the following problems that I encountered in the model I created by myself, which is too current.

    These thermal networks are provided by the vendor.

    Then I would like to ask if there is no effect on the results obtained by the simulation if these parameters are not in the model. In other words, this parameter only affects the junction temperature of the device
