Abstract
A coaxial surge protector includes a housing in which is situated a transmission line in the form of a two-sided printed circuit board. The surge protector includes input and output signal connectors mounted on a housing and connected to the transmission line, and a gas discharge tube electrically coupled between the transmission line and circuit ground. A thermally activated shunt assembly is thermally coupled to the gas discharge tube and senses when the gas discharge tube is in an overheating condition. Upon such condition, the shunt assembly provides an electrically conductive shunt in parallel with the gas discharge tube to divert current flowing through the gas discharge tube to flow through the shunt assembly to ground in order to minimize further overheating of the gas discharge tube.
