Triggered Spark Gaps
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.
- Tight main static breakdown voltage tolerance (±10% – TA & TB series)
- Adjustable main static breakdown voltage (TG221 to TG226)
- Rugged ceramic-metal construction
- Refractory metal electrodes
- Corrosion-resistant stainless steel external surfaces (TB series)
- High Current Surge Generators
- Exploding Bridge Wire Systems
- Crowbars
- Flashlamp Triggers
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.
- Tight main static breakdown voltage tolerance (±10%)
- Long-life tungsten or molybdenum electrodes
- Rugged ceramic-to-metal or glass-to-metal construction
- Test Equipment
- Video Displays
- Pulse Generators
- Medical Electronics

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.
