Claim 12:
13. A semiconductor unit, comprising:
a semiconductor device including a transistor, the transistor including a first terminal for a battery, a second terminal for an inverter circuit, and a control terminal; and
a controller connected to the control terminal and configured to control on-off operations between the first terminal and the second terminal, wherein
the controller controls a voltage between the first terminal or the second terminal of the transistor and the control terminal the of the transistor to be less than or equal to a voltage at which a current flowing to the transistor is saturated at a predetermined current,
the transistor further includes a temperature-sensing diode,
the transistor is provided as a semiconductor chip, and
the temperature-sensing diode is arranged in a central portion of a front surface of the semiconductor chip of the transistor.
