A lightning suppressor

Abstract

The utility model provides a thunder and lightning suppressor, including 15~20um mesa pipe core, one end of two 15~20um mesa pipe core is connected with electrode lead respectively, is connected through a plurality of 3~6um mesa pipe core of stack between two 15~20um mesa pipe core, be equipped with passivation protection layer on the lateral wall of electrode lead, 15~20um mesa pipe core, 3~6um mesa pipe core, still include the filling layer of plastic package in the suppressor outside. Adopt diffusion technology to make PN junction, guarantee the parameter stability of single pipe core, through a plurality of pipe core series connection package, are connected in the both ends of protection circuit. In the circuit play the role of clamping, clamp the voltage of circuit both ends near the forward voltage drop, avoid the subsequent circuit to bear excessively high voltage. When thunder and lightning pulse arrives, transient voltage rises over the total forward voltage drop of suppressor momentarily, and the suppressor is rapidly conducted, forms low impedance path, and the transient current is guided to the ground wire after conduction, and the sensitive device is protected.
