Bourns releases new Gas Discharge Tube series for use with high-speed detectors
Bourns has announced the release of the 2020 T Series fast response Gas Discharge Tubes (GDTs) designed for use with Bourns® TBU® High-Speed Protectors.
The newly released part numbers and specifications are:
Part Number | DCBD (V) | Size (mm) | 5 kV/µs Impulse Voltage (V) | Used with TBU® Series |
---|---|---|---|---|
2020-15T | 60 | 500 | TBU-CA050 | |
2020-23T | 180 | 8 x 11.2 | 650 | TBU-CA065 |
2020-42T | 360 | 850 | TBU-CA085 |
The 2020 T Series and Bourns® TBU® High-Speed Protectors are an ideal protection solution for a broad number of industrial applications as well as telecom applications requiring GR-1089 or ITU-T K.21 compliance. The Bourns® 2020 T Series is also available with an optional fail-short mechanism for applications requiring UL safety standard compliance.
These GDT devices provide coordinated overvoltage protection for the specified TBU® protector models shown in the above table. Together, the GDT and TBU® protectors provide extremely fast overcurrent protection (OCP) and overvoltage protection (OVP) against electrical transients. When exposed to a transient event, the TBU® protector will transition into a current-blocking condition in less than one microsecond at the rated current. When needed, the GDT will transition into conduction at a voltage below its maximum impulse rating, protecting the TBU® device from overvoltage and shunting the excess surge energy to ground. Once the transient subsides, the GDT and TBU® device will reset to their normal off-state modes of operation.
