A semiconductor device including a normally-on SI thyristor, and a MOSFET connected in cascade with the SI thyristor. The gate of the SI thyristor is connected to the source of the MOSFET. This arrangement makes it possible to turn the device on and off by controlling only the voltage gate of the MOSFET, obviating a current to maintain the on state of the device. The device needs little driving energy and has a low on state voltage and a high switching speed. It can readily be integrated into one chip.
