Triggered Spark Gaps

High Energy Devices’ TX Series, TA/TB/TG221-226 Series and TG Three-Electrode Legacy Series, which have main static breakdowns up to 60kVdc, are high energy spark gaps which are capable of switching stored energy in a fraction of a microsecond upon command. These Triggered Spark Gaps require no standby power, are extremely rugged and require only a low energy, high voltage pulse. Applications include crowbars, exploding bridge wire systems, and xenon flashlamp triggers. High Energy Devices’ miniature Triggered Spark Gaps, which have main static breakdowns between 2.0 and 10.0kVdc, have been designed for applications where cost is a major consideration, but high reliability switching is still required.

TA/TB/TG221-226 Series

High Energy Devices’ Triggergaps are high energy spark gaps that are capable of switching stored energy in a fraction of a microsecond upon command. Triggergaps require no standby power, are extremely rugged, and require only a low-energy, high-voltage triggering pulse. The miniature TA Series (1.0-15.0kV) provides switching capability for pulses with energy content as high as 50 joules. The larger TB Series (2.5-25.0kV) will reliably switch pulses with up to 300 joules of energy. The TG221 to 226 (1.0-60.0kV) can switch pulses with energy contents of up to 6,000 joules and feature adjustable main static breakdown voltages.

TG Three-Electrode Legacy Series

High Energy Devices’ TG Legacy Series of three-electrode triggered sparkgaps (cold cathode thyratrons) are designed for switching high levels of stored energy in fractions of a microsecond, on command, using low energy control pulses.

TX Series

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.
