Lumped parameter model of pn-junction diode

Everything is a nonlinear function of voltage and/or current. A "lumped" model can exist at only a single bias condition. Thus what value could it be? ...Jim Thompson

| 1962 | I love to cook with wine. Sometimes I even put it in the food.

Either that or the "lumped" model is Id = Iss * (exp(V/Vt) - 1).

(I think I got that right).

I think that's right Tim, Most diodes have a 'non-ideality factor' of about 2, so there's a factor of ~2 somewhere in the exponential. (I can't recall if numerator or denominator.) You could then add some series resistance. And then the voltage dependent junction capacitance.
