ABSTRACT:
A protection semiconductor component includes at least two pairs of main Shockley diodes, each pair including two parallel diodes, head-to-tail connected between a front surface metallization and a rear surface metallization, the rear surface metallization being common to the two pairs of diodes. Each of the main diodes whose blocking junction corresponds to a distinct well on the side of the front surface is associated with at least one auxiliary Shockley diode having the same polarity and a lower triggering threshold, the triggering of one auxiliary diode thus causing the triggering of the other auxiliary diode and of the associated main Shockley diodes.
