摘要: A transistor (2) is provided on a semiconductor substrate (8). A temperature detection diode (4) for monitoring temperature of an upper surface of the semiconductor substrate (8) is provided on the semiconductor substrate (8). An external electrode (7) is connected in common to an emitter (E) of the transistor (2) and a cathode (K) of the temperature detection diode (4). Therefore, an external electrode for the cathode (K) of the temperature detection diode (4) can be removed, and thus the device can be reduced in size and improved in terms of ease of assembly.
