Abstract
In an embodiment, a method for testing a functional integrity of a transistor component, the method includes causing a first change of a charge state of an internal capacitance between control terminals of the transistor component; determining a capacitance value of the internal capacitance based on the first change of the charge state; causing a second change of the charge state of the internal capacitance; and evaluating a resistance value of an internal resistance between the control terminals based on the determined capacitance value and the second change of the charge state.
