The Bourns 2026 series gas discharge tubes (GDTs) provide reliable surge protection for telecommunications, industrial, commercial, and consumer electronics. These 3-pole GDTs offer a balanced TRIGARD design, high surge current rating, and stable breakdown throughout their lifespan. They are suitable for applications requiring robust protection against voltage transients and are available in RoHS compliant versions. An optional Switch-Grade Fail-Short device is available for enhanced safety, activating at 215°C – 217°C to provide a high conductive path to ground in case of thermal overload. Users should verify actual device performance in their specific applications.
