Abstract
The semiconductor device is composed of a thyristor and a MOSFET (801) cascode-connected. The thyristor includes a bipolar transistor (803) cascode-connected with the MOSFET (801), the base (p.sup.-- semiconductor region (704)) of which is adapted to be punched through by the application of a working voltage. Thus, the thyristor can easily be latched and unlatched in response to the turn-on and turn-off of the MOSFET (801). Thus the semiconductor device can be securely on/off controlled only by the single gate (G) of the MOSFET. By using such semiconductor device as a switching element (910) in a flash control device, a high performance flash control device with high flashing efficiency can be implemented.
