ABSTRACT:
An overvoltage protection device is employed to protect the low power semiconductor components of a circuit against overvoltages applied at the connection leads of the circuit. The device has at least two branches that are each connected between a common point and one of the connection leads of the circuit. Each branch includes a diode thyristor that is self-igniting in response to a particular overvoltage and an associated diode that is connected in opposed relation to the diode thyristor. The diode thyristors are aligned to conduct in the same direction with respect to the common point of connection. An additional branch may be connected between the common point and ground.
