Abstract
Embodiments of the invention are related to a power transistor and a method for controlling a power transistor. In one embodiment a power transistor comprises a power semiconductor body with a plurality of power transistor cells each having a control electrode and a current path. The power transistor furthermore comprises a temperature sensor formed by at least one transistor cell in the power semiconductor body whose control electrode is coupled to one electrode of the current path forming a reversed biased pn-junction.
