The XT Series is a 2-terminal bi-directional, voltage triggered switch designed for Xenon HID 'hot re-strike' circuits such as those found in automobiles. Switching voltages for the devices are fixed depending on the part number selected.

The gas plasma trigger technology offers very fast switching speeds, resulting in significantly better di/dt values when compared to silicon based SIDAC devices. Due to the high switching voltage of the devices, step-up transformer sizes and specifications can be reduced, saving cost, size, and weight.

  • RoHS compliant
  • 2 terminal configuration
  • Very high switching speed once switching voltage has been reached, resulting in high di/dt to be generated enabling the best performance to be extracted from ignition transformers
  • High lifetime and stability
  • Switching performance is virtually unaffected by changes in ambient temperature
  • Tape and Reel to EIA 481-1


  • This product is optimized for Xenon HID ‘Hot re-strike’ circuits which require a very high number of operations at high current levels. The switching time is typically 10nS for the best possible efficiency
