Abstract: The present description concerns a circuit of protection against overvoltages appearing during a protection against overcurrents comprising: a first diode and a second diode having their cathodes coupled to a first node; a first transient voltage suppressor diode having its cathode coupled to a second node and having its anode coupled to the anode of the first diode; a thyristor having its cathode coupled to the anode of the second diode, having its anode coupled to the second node, and having its gate coupled to the anode of the first diode; and a switch having a first terminal coupled to the first node.
