Description
The simple diode is a two-terminal electronic (Anode and Cathode) component that conducts current which, passing through a junction, can only go in one direction, called the forward direction.
Current trying to flow the reverse direction is blocked.
It consists of the diode itself and an parallel ohmic resistance R. The diode formula is:
If the exponent v/Vt reaches the limit maxex, the diode characteristic is linearly continued to avoid overflow.
Please note: In case of useHeatPort=true the temperature dependence of the electrical behavior is not taken into account yet. The parameters are not temperature dependent.
