This article addresses the possibility of forming built-in overvoltage self-protection elements in high-voltage semiconductor thyristors with local proton irradiation of the main control electrode area, and shows that the thyristors with such self-protection elements safely and reliably turn on in typical breakdown situations with blocking voltage overload.
