Three-Electrode

Our three-electrode spark gaps are fire-on-command devices. These comprise hermetically sealed gas-filled switches and are available with DC hold-off voltages ranging from 3 to 50 kV.Three-electrode spark gap applications include medical lithotripsy, crowbar circuits, high di/dt switches for laser firing and high energy switches.

GXG Series

The GXG Series of triggered three-electrode spark gaps are gas discharge tubes, hermetically sealed in a ceramic/metal envelope. Tubes with a DC hold-off voltage in the standard range 15 to 50 kV are available. Device breakdown voltage is signified by numerals (expressed in hundreds of volts) following the series type identifier: e.g. GXG350L has a 35 kV DC hold-off voltage capability. The operational voltage range for the GXG Series is 40% to 80% of DC hold-off voltage.

Typical Applications

• Medical lithotripsy
• Crowbar circuits
• High di/dt switching
• High voltage switches for laser firing
• High energy switches

GX3500 Series

The GX3500 Series of triggered three-electrode spark gaps are gas discharge tubes, hermetically sealed in a ceramic/metal envelope for use in air. Tubes with a DC hold-off voltage in the standard range 15 to 50 kV are available. Device breakdown voltage is signified by numerals (expressed in hundreds of volts) following the series type identifier: e.g. GX3500-400 has a 40 kV DC hold-off voltage capability. The operational voltage range for the GX3500 Series is 40% to 80% of DC hold-off voltage.

Typical Applications

• Crowbar circuits for high power travelling wave tubes, power klystrons and similar devices
• High voltage switches for laser firing
• General switching applications GXT Series

GXT Series

The GXT Series of triggered three-electrode spark gaps are gas discharge tubes, hermetically sealed in a ceramic/metal envelope. Tubes with a DC hold-off voltage in the standard range 3 to 25 kV are available.
