The Diode device model () is a large-signal model for a diode. It is an advanced device model and no thorough description and motivation of the many input parameters are attempted here. The interested reader is referred to for more details on semiconductor modeling within circuits. Many device manufacturers provide model parameters for this diode model. For any particular make of diode, the device manufacturer should be the primary source of information.

Specify two Node names for the positive and negative nodes for the Diode device.

Specify the Model Parameters. Reasonable defaults are provided but for any particular diode, the device manufacturer should be the primary source of information.
