Abstract:
A thyristor has a radiation-sensitive breakdown structure (20), a gate electrode (92) that is placed at a distance from the latter in a lateral direction and an ignition stage structure having at least one ignition stage (51, 91) equipped with an n-doped auxiliary emitter (51), which forms a pn-junction (55) together with the p-doped base (6), 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 (92), a contact ram (200) that is adapted to the geometry of the gate electrode (92) 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 (92) or the electrically conductive electrode (105, 201) is monitored.
