Description
~~~~~~~~~~~

This component consists of a simple diode parallel with an ohmic
resistance ( ** *R*** ). The current ( ** *I*** ) passing through this
component is defined as a function of the voltage across the ports (
** *V*** ):





where ** *Ids*** and ** *Vt*** are the saturation current and the
voltage equivalent of temperature, respectively. If the exponent
reaches a certain limit ( **Max exponent for linear continuation**),
the diode characteristic becomes linear to avoid overflow.
