ABSTRACT:
A thyristor has a semiconductor body exhibiting an n-p-n-p layer sequence with the small n-emitter and the p-emitter being contacted by first and second electrodes. The p-base layer has a third electrode connected to the first electrode through a first current source connectible with a first polarity. For triggering or quenching the thyristor as quickly and efficiently as possible, the n-base layer has a fourth electrode connected to the second electrode through a second connectible current source, the second current source being connectible to the fourth electrode with a second polarity opposite the first polarity.
