  • Integrated power switch structure having a vertical thyristor controlled by a lateral MOS transistor
    Patent number: 5413313
    Abstract: An integrated power switch structure comprises a lateral MOS transistor (3) and a lateral or vertical thyristor (2). The drain-source path of the lateral MOS transistor (3) is in series with the cathode-anode path of the thyristor (2). In order to ensure that the power switch structure reliably switches on and off with great dielectric strength and low switch-on resistance, at least the source electrode of the lateral MOS transistor (3) is insulated against the substrate (7) by means of a buried oxide layer (8) in accordance with the present invention.
