摘要： A circular semiconductor wafer includes a thyristor surrounded by a diode through an annular V-shaped groove-filled with glass. That face of the wafer near to the extremity of the groove is disposed on a molybdenum plate through a brazing layer. A base layer on both faces of the wafer has those portions extending through the associated emitter region at predetermined positions to be exposed to the wafers face to form degenerate P-N junctions on and adjacent that face with the adjacent emitter portions. The brazing layer and the opposite electrode for the thyristor include small openings looking the exposed portions of the base layers and the adjacent emitter portions respectively.

摘要： A main thyristor is serially connected to a load across an AC source. A thermally sensitive thyristor is connected at the anode to the anode of the main thyristor through a resistor and at the cathode to the gate electrode of the main thyristor and responds to an ambient temperature exceeding a predetermined magnitude to be conducting. When conducting, the thyristor switches the main thyristor to its ON state. Alternatively, the anode of the thyristor may be connected to the junction of two series resistors connected across the anode and cathode of the main thyristor. The conducting thyristor turns the main thyristor off.
