Start a SimulationSPICE model for discrete devices
I would like to inquire whether the parasitic parameters provided in the SPICE model for discrete devices, such as Ls1, Ls2, and Lg, include the long leads of the discrete device, or if they only account for the path from the die to the root of the pins. Additionally, in practical use, is the loop inductance contributed by discrete devices generally larger or smaller than the values in the model? According to the parameters extracted from finite element simulation (excluding the device) and double pulse test results, it seems that the total inductance of the C3M0021120K is around 12nH. Could you confirm whether this is reasonable?
