Gas Discharge Tube (GDT) Surge Arrestors

Bourns® Gas Discharge Tube (GDT) Surge Arrestors safeguard an ever-increasing variety of electronic equipment. Bourns has over 50 years of experience inventing and producing GDT devices with low capacitance, extended life, and high surge current handling. Bourns engineers keep innovating GDT technology with industry-leading designs including the GDT Series featuring FLAT® technology.

Standardized design with minimal capacitance and insertion loss, GDT protects sensitive equipment from dangerous voltages. Some models have Switch-Grade Fail-Short technology for better surge protection.

Bourns manufactures 2- and 3-electrode GDT devices. 2-electrode devices are used to provide line to ground or line to line protection (1 to 2). A 3-electrode GDT can provide protection from line to line (1-2) as well as line to ground (1 to 3, 2 to 3) in a single device.

Standard GDTs (75-600 V) are available in 2- and 3-electrode versions. High voltage GDTs (800-7200 V) are mostly offered in 2-electrode devices with a few 3-electrode devices. Specialized GDTs are available in high current, hybrid, and FLAT® technology versions to provide a broader range of protection demands.
