The object of the invention is a gas discharge tube for surge protection of different electronic devices, more precisely a gas discharge tube with a very thin design. The flat gas discharge tube includes a ceramic insulator (1), two metal electrodes (2,3), gas filling and a graphite coating (5) on the ceramic insulator, and is characterized in that the ceramic insulator is cylindrically shaped and has a wider ring (1a), a narrow ring (1b) with metallized layers (6,6') and a wider ring (1d), which is formed into a tip in the direction towards the centre of the ceramic insulator, wherein the distance between the planes with metallization is smaller than or equal to the distance of the inner wall (1d', 1d") of the ceramic tip. The insulation distance on the ceramic insulator between the electrodes is increased with the shape of the ceramic insulator and the shape of electrodes, which enables optimal performance of the gas discharge tube. |
