Active protection circuit arrangement A circuit arrangement for protecting integrated semiconductor circuits from electrical pulses or electrical overvoltages is proposed, said circuit arrangement having an RC element which comprises the series circuit formed from a first resistor (R 1; R 10 ) and a capacitance (C 1; C 10 ) and is connected between two supply potential lines (VDD, VSS), having a chain of inverters (I 10 -I 12 ) which are connected in series behind one another, the input of said chain being connected to the junction point between the first resistor (R 1; R 10 ) and the capacitance (C 1; C 10 ), and having a protection transistor (ST) whose control input is connected to the output of the inverter chain and whose outputs are connected to the two supply potential lines (VDD, VSS).
