The 2026-09-C2FLF is a 3-pole gas discharge tube (GDT) designed for transient overvoltage protection with a DC sparkover voltage of 90 V at 100 V/s. This Bourns TRIGARD® device features a compact form factor of approximately 8 mm diameter and 11 mm length, with a fail-short mechanism (F designation) and RoHS-compliant construction (LF designation). The tube exhibits high surge current capability, supporting impulse discharge currents up to 40,000 A (8/20 µs) for single operations and 1,000 A (10/1,000 µs) for over 400 operations, with stable breakdown characteristics throughout its operational life. It is UL recognized and suitable for telecommunications, industrial electronics, commercial electronics, consumer electronics, and aircraft/military applications where reliable protection against transient surges is essential.
