TX Series
Triggered Spark Gaps
Features * Rugged ceramic-metal construction * Short delay times * Miniature size * High reliability
Applications * High current surge generators * Military ordnance - Exploding bridge wires - Exploding foil initiators - Slapper detonators - Electronic safe and arm * Crowbars * Flashlamp triggers * Rocket motor ignitions * Missile stage separation * Furnace ignitions
Description The TX is a series of miniature triggered spark gaps designed for high reliability switching with Main Static Breakdown's between 2.0 and 10.0kVdc and are available at relatively low cost. This series of gaps is capable of switching stored energy in a fraction of a microsecond upon command. Trigger gaps use no standby power, are extremely rugged and require only a low energy high voltage trigger pulse. They are hermetically sealed at high braze temperatures and will withstand rugged environmental conditions.

The trigger voltages given in these tables are the minimum triggering voltages necessary for triggering at the corresponding applied voltage limits. As the applied voltage increases, the trigger voltage required for triggering decreases. It is assumed that the trigger is applied across the trigger and adjacent main electrodes. Higher trigger voltages are required if it is applied across the trigger and opposite main electrodes. End point for the life testing is a 20% reduction in the main static breakdown voltage. The Pulse Energy is the stored energy which the spark gap can dissipate per discharge, during intermittent duty, without permanently changing its breakdown ratings by more then 10%. The principal effect of excessive pulse energies is rapid electrode erosion and change in breakdown characteristics.
