Abstract
A semiconductor device including: a semiconductor substrate; a temperature sensing unit provided on a front surface of the semiconductor substrate; an anode pad and a cathode pad electrically connected with the temperature sensing unit; a front surface electrode being set to a predetermined reference potential; and a bidirectional diode unit electrically connected in a serial bidirectional way between the cathode pad and the front surface electrode is provided. The output comparison diode unit may be arranged between the anode pad and the cathode pad. The temperature sensing unit may include a temperature sensing diode, and the output comparison diode unit may include a diode connected in inverse parallel to the temperature sensing diode.
