LTspice model question: parasitic parameters associated with discrete packages

Hi Wolfspeed experts,


According to the document, LTspice model has a parasitic component associated with the package (gate, source, drain and kelvin). When I check the parameters described in the library file (C3M0016120K.lib for this case), I found:

Ls1 and R_Ls1 : inductance & resistance of source pin & wires

Ls2 and R_Ls2 : inductance & resistance of kelvin pin & wire

Lg and R_Lg : inductance & resistance of gate pin & wire

Ld and R_Ld : inductance & resistance of drain pin & wires


Here's the question, what parameters Rv and Lv and R_gg refer to?


Thank you for your support.

Best Regards,

Hiroshi
