Q_NPNBJT

Bipolar junction transistor

Information

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

The model Q_NPNBJT is a NPN bipolar junction transistor model: Modified Gummel-Poon.

The models from the package Semiconductors accesses to the package Internal where all functions,

records and data are stored and modeled that are needed for the semiconductor models.

The package Semiconductors is for user access but not the package Internal.
