Gas discharge tubes (GDTs) are used to protect personnel and sensitive equipment from hazardous transient voltages. Bourns' GDTs are used in primary and secondary applications and can withstand multiple applications of high surge current energy in excess of 25 kA.
Bourns offers standard 8 mm GDTs and a 5 mm mini series GDT in two and three electrode versions that it says feature long service life and low capacitance and insertion loss. An optional, proprietary 'Switch-Grade Failshort' is offered on the three-electrode version to provide superior protection from thermal runaway.
These GDTs meet or exceed virtually all industry specifications regulating the use of gas discharge tubes, says the manufacturer. Bourns also offers Telecom Design Kits that include this product line.
