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. Notes:

  • UL recognized component, UL File E153537.
  • Model number marking on tube: 2029-xxxV.
  • Surface Mount (SM) parts may show a temporary increase in DCBD after the solder reflow process. Most devices will recover within 24 hours time. It should be noted that there is no quality defect nor change in protection levels during the temporary change in DCBD.
  • Sparkover limits ± 25% and IR >108 Ω after life.
  • At delivery AQL 0.65 Level II, DIN ISO 2859.
  • Bourns recommends reflowing surface mount devices per IPC/JEDEC J-STD-020 rev D. (2) Network applied. (3) DC Sparkover may exceed ±20 % after discharge, but will continue to protect without venting.
