Abstract
A spark gap device includes planar electrodes between which in operation a discharge occurs. The electrodes are spaced apart by a ceramic member and are arranged in substantially parallel, different, planes. A trigger electrode is included for switching the device into conduction. The device has a low inductance structure which is compatible with stripline circuits. In another embodiment of the invention the planar electrodes and the trigger electrode are located in the same plane on a common substrate.
