The GDT products prevent injury to personnel and damage to equipment from transient voltage disturbances by reacting as fast as a crowbar device. When an electrical surge exceeds the breakdown voltage of the device, the gas inside the GDT becomes ionized and conduction takes place within a fraction of a microsecond. When the voltage returns to normal operating levels, the GDT returns to its high impedance state and is transparent to the circuit.
The Bourns GDT product line features industry leading 3-electrode balanced Triguard® and 5mm 2-electrode products. Our patented surtab grade failsafe design can be combined with various lead configurations to allow customers multiple applications with the industry's lowest contact resistance in short circuit mode.
Bourns GDTs can be used in many applications, including telecommunications, CATV/Broadband applications, RF antennas and equipment, consumer electronics, Printed Circuit Boards, Automotive and many more. All products exceed Telcordia, REA, IEEE, ITU-T and IEC specifications and requirements, and are UL recognized components.
Bourns is launching the 2027 Series full size 2-Pole GDTs, the 2026 full size Series 3-Pole GDTs, the MSP Series Multi-Stage Protector, the 2035/2037 Series Miniature 2-pole GDT, the 2036 Series Miniature 3-Pole GDT and the 4010 and 4020 Surge Protector Test Sets. All 2-Pole GDTs are available from 90 to 600V, while the 3-Pole Series tubes are available from 75 to 600V Break Down Voltages.
