  • Semiconductor element for electric power with a diode for sensing temperature and a diode for absorbing static electricity
    Patent number: 6291826
    Abstract: A first diode part (1B) for sensing junction temperature and a second diode part (1C) for absorbing static electricity that are included in a semiconductor element (1) for electric power are formed within the same substrate together with a semiconductor element part (1A) for electric power. Moreover, the number of a plurality of second diodes (1CD) constituting the second diode part (1C) is equal to the number of a plurality of first diodes (1BD) constituting the first diode part (1B). In addition, a capacitor (11) for reducing the impedance is disposed between the input terminals of a forward direction voltage fall operating amplifying circuit part (4) of a controlling circuit part (8). Here, it is effective to form an LC low pass filter as well by covering a forward path side relay lead part (9A) and a backward path side relay lead part (9B) with one tubular ferrite core.
