| Zusammenfassung: | The invention discloses a surge protector, which belongs to the technical field of lightning surge protection, and comprises a first switch tube, a second switch tube, a first voltage stabilizing diode and a first resistor, the cathode of the first voltage stabilizing diode is connected with the grid electrode of the first switch tube, the source electrode of the first switch tube is connected with the collector electrode of the second switch tube, and the first resistor is connected with the second switch tube. The drain electrode of the first switch tube is connected with the first end of the first resistor, the first end of the first resistor is connected with the gate electrode of the second switch tube, and the second end of the first resistor is connected with the emitting electrode of the second switch tube and the anode of the first voltage stabilizing diode. The clamping voltage of the surge protector and the surge protection module hardly changes along with the current; the circuit is simple in stru |
