Abstract

The embodiment of the invention discloses a piezoresistor of an integrated gas discharge tube. The piezoresistor comprises a first cylindrical electrode, a first hollow pipe, and a piezoresistor body in a flat plate structure, or a cup-shaped piezoresistor body with a concave longitudinal section, wherein the first cylindrical electrode, the first hollow pipe and the piezoresistor body in a flat plate structure or the cup-shaped piezoresistor body are hermetically connected to form an airtight cavity in which an inert gas is stored. The piezoresistor further comprises a second cylindrical electrode in the airtight cavity, the inner surface and outer surface of the cup-shaped piezoresistor body are coated with electrode layers made of conductive materials, the electrode layer on the inner surface serves as a common electrode of the cup-shaped piezoresistor body and the gas discharge tube, so that the piezoresistor body and the gas discharge tube are connected in series to achieve the purpose of excess voltage protection, the piezoresistor body and the gas discharge tube are integrated, so that the problems of low excess voltage protection performance and poor stability of the piezoresistor body are solved, and the follow current problem of the single follow current in application of a power circuit is also solved.

Description

technical field [0001] The application relates to the field of overvoltage protection, in particular to a piezoresistor integrated with a gas discharge tube. Background technique [0002] In the field of overvoltage protection technology, the varistor has an electrical characteristic. When the voltage applied to the varistor exceeds its own threshold, the resistance of the varistor will become smaller, so that the voltage flowing through the varistor When the current surges instantaneously, the current flowing through other circuits is basically normal, thereby reducing the impact of overvoltage on subsequent sensitive circuits. Therefore, varistors are usually used to suppress the abnormal overvoltage that often occurs in the circuit and protect the circuit from overvoltage damage. . However, when the voltage applied to the varistor is lower than its own threshold, there is still a small current flowing through the varistor, and the current will increase with the increase ...
