ABSTRACT:
A monolithic component for protection against over-currents liable to occur on a line in series with which is connected a detection resistor, comprises a first cathode-gate thyristor associated with an avalanche diode and a second anode-gate thyristor of the gate triggering type or forward breakover type, its breakover voltage being substantially equal to the avalanche voltage of the avalanche diode.
