Abstract
A semiconductor module, including a semiconductor chip that includes a switching device having a control electrode, and a control terminal connected to the control electrode, a first resistance being formed between the control electrode and the control terminal and having a positive temperature coefficient, and a second resistance connected to the control terminal, the second resistance having a negative temperature coefficient. A temperature coefficient of a combined resistance at the control terminal is zero or negative.
Claims12
A semiconductor module comprising:
- a semiconductor chip that includes a switching device having
- a control electrode, and
- a control terminal connected to the control electrode,
- a first resistance being formed between the control electrode and the control terminal, the first resistance having a positive temperature coefficient;
- and
- a second resistance connected to the control terminal, the second resistance having a negative temperature coefficient, wherein
- a temperature coefficient of a combined resistance at the control terminal is zero or negative, wherein
- the second resistance is spaced apart from the semiconductor chip by a predetermined distance, such that a temperature of the second resistance starts to rise after a predetermined time period has elapsed since a temperature of the semiconductor chip starts to rise.
