Thyristor with several semiconductor zones - has three zones one forming Schottky diode with its electrode, and middle zone forming gate

摘要

The zones are of different conduction types, and the outer zones have electrodes connected to a voltage source. A current flows between the outer electrodes, depending on a control signal applied through a control electrode to one of the inner zones. Three semiconductor zones (1-3) are provided. The first zone (1) outer electrode (4) forms with it a Schottky diode. The end electrode (K) on the third zone (3) forms with it a resistive contact, and the control terminal (G) is connected to a gate (6) provided on top of a thin insulating layer (5) covering the second zone (2).
