Information

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

Since the simple bipolar transistor model does not have base or collector resistances both are added in this component. Additionally, a capacity is added to the base pin. See the schematic for more details. In such a way the transistor model can be enhanced to become more common.
