2026 Series - 3-Pole Gas Discharge Tube

*RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011. Specifications are subject to change without notice. The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time. Users should verify actual device performance in their specific applications. Test Methods per ITU-T K.12, IEEE C62.31 and IEC 61643-311 GDT standards.

An optional Switch-Grade Fail-Short device is available. The optional Fail-Short assembly will activate at a temperature of 215 °C – 217 °C to provide a high conductive path to ground in case of a thermal overload. GDTs equipped with the optional Fail-Short device should be soldered either manually at a temperature that is below the activation temperature of the Fail-Short mechanism, or using a selective soldering process that does not exceed 210 °C. Notes:

  • Model number marking on tube: 26-xxx V.
  • The rated discharge current for TRIGARD® Gas Discharge Tubes is the total current equally divided between each line to ground.
  • Sparkover limits after life ±25 %, IR >108Ω (-25 %,+30 % for Model 2026-07, 2026-09 and 2026-60).
  • Line to Line voltage is approximately 1.8 to 2 times the stated Line to Ground breakdown voltage.
  • At delivery AQL 0.65 Level II, DIN ISO 2859 (2) Network applied. (3) DC Sparkover may exceed ±25 % after discharge, but will continue to protect without venting. *RoHS COMPLIANT LEAD FREE *RoHS COMPLIANTVERSIONS AVAILABLE LEAD FREE VERSIONS ARE RoHS COMPLIANT*Characteristic Model No. 2026-30 2026-35 2026-40 2026-42 2026-47 2026-60 DC Sparkover ±20 % @ 100 V/s 300 V 350 V 400 V 420 V 470 V 600 V Impulse Sparkover (1)
