3404 miniature gas discharge tube (GDT) technology

HUBER+SUHNER miniature gas discharge tube protectors are designed to protect against multiple electromagnetic threats including SURGE, NSL, ESD or (H)EMP.

The unique design guarantees excellent dynamic protection performance and also includes a fixed integrated gas discharge tube (GDT). Miniature GDT protectors have a bulkhead feed-through configuration and can be easily installed in place of a standard waterproof bulkhead coaxial connector to harden existing equipment. 


  • Waterproof interface even in un-mated conditions
  • Low contact resistance between protector body and mounting wall
  • Space saving in-line design
  • Broadband DC to 3 GHz
  • Surge current handling capability up to 5 kA (8/20 µs)
  • DC continuity for remote powering
  • Fix installed GDT, static spark over-voltage nom. 150 V
  • In conformity with the LPZ concept at the boundaries from 0B – 1 and higher
Different or additional protectors need to be used for lightning protection.
