Abstract
A thyristor has a radiation-sensitive breakdown structure (), a gate electrode () that is placed at a distance from the latter in a lateral direction and an ignition stage structure having at least one ignition stage () equipped with an n-doped auxiliary emitter (), which forms a pn-junction () together with the p-doped base (), the thyristor being both electrically and radiation-ignited. In a method for contacting a thyristor that can be ignited by radiation with a gate electrode (), a contact ram () that is adapted to the geometry of the gate electrode () is pressed against the thyristor. In a method for monitoring the ignition of a thyristor that is ignited by incident radiation, the electric voltage that is applied to the gate electrode () or the electrically conductive electrode () is monitored.
