    摘要: An RC-IGBT according to the invention includes a high electric field cell formed in a region surrounded by an IGBT cell or in a region surrounded by a diode cell, and an n+ diffusion layer formed at a position opposed to the high electric field cell, the position being on a second main surface of an n− type drift layer. The high electric field cell has a higher maximum electric field intensity generated when a voltage is applied between main terminals than maximum electric field intensities of the IGBT cell, the diode cell, and a withstand voltage holding structure. Additionally, a p+ type collector layer and the high electric field cell fail to overlap with each other in a direction vertical to a first main surface of the n− type drift layer in a plane view.

    摘要: Provided is a sensor device that suppresses a malfunction caused by a negative surge or a voltage drop. A sensor device includes a sensor element having an electrical characteristic varying according to a physical amount, a signal processing circuit configured to process an output signal of the sensor element, a transistor element interposed between a power source terminal and the signal processing circuit, a resistive element configured to connect a drain and a gate of the transistor element, or a collector and a base of the transistor element, and an element having threshold voltage for connecting the gate or the base of the transistor element to a GND. The element regulates current flowing from the resistive element in a direction of the GND, in a case in which supply voltage to the signal processing circuit falls below the threshold voltage.
