Abstract
The present invention relates to a normally-on bidirectional switch, including, in parallel between two power terminals of the switch, a first cathode-gate thyristor, the anode of which is connected to a first power terminal, a second anode-gate thyristor, the anode of which is connected to a second power terminal, and a resistor in series with a controllable switch, the midpoint of this series association being connected to the respective gates of the two thyristors. The present invention also provides a monolithic integration of the switch.
