Abstract

L'invention concerne un thyristor autoprotégé contre les surtensions par le mécanisme d'avalanche, la protection résultant d'une nervure annulaire (22) formée au laser dans la surface supérieure du thyristor et pénétrant dans une région de base du thyristor afin que la jonction de blocage direct soit déformée vers la jonction de blocage inverse en-dessous de la rainure annulaire; l'invention concerne également le procédé de fabrication de ce thyristor.
