This information is part of the Modelica Standard Library maintained by the Modelica Association.

The PMOS model is a simple model of a p-channel metal-oxide semiconductor FET. It differs slightly from the device used in the SPICE simulator. For more details please care for H. Spiro.
A heating port is added for thermal electric simulation. The heating port is defined in the Modelica.Thermal library.
The model does not consider capacitances. A high drain-source resistance RDS is included to avoid numerical difficulties.
