Abstract

An arrangement for the protection of a semiconductor device against overvoltages and/or overloads, establishing a short circuit in its input, comprising a thyristor or similar semiconductor device controllable, connected through said input, and at least a Zener diode or static device similar that responds to the current and/or the voltage connected to said apparatus to detect overvoltages and/or overcurrents created in them and to the semiconductor device to apply a control signal, being born conductor is the last device in the case of being detected one , condition, overvoltage or overcurrent.
