This is an ideal semiconductor which is

open (off), if it is reversed biased (voltage drop less than 0)
closed (on), if it is conducting (current > 0).

This is the behaviour if all parameters are exactly zero.

Note, there are circuits, where this ideal description with zero resistance and zero conductance is not possible. In order to prevent singularities during switching, the opened semiconductor has a small conductance Gon and the closed semiconductor has a low resistance Roff which is default.

The parameter Vknee which is the forward threshold voltage, allows to displace the knee point
along the Gon-characteristic until v = Vknee.

Please note: In case of useHeatPort=true the temperature dependence of the electrical behavior is not modelled.
