GAS DISCHARGE TUBES Bourns Releases New Gas Discharge Tube 2030 T-Series Riverside, California - May 22, 2012 - Bourns is pleased to announce the release of the Model 2030 T-Series fast response Gas Discharge Tubes (GDTs) designed for use with the Bourns® TBU® High-Speed Protectors (HSPs). The newly released part numbers and specifications are: Part Number DCBD Size 2030-23T 2030-42T 185 V 360 V 5 x 7.3 mm 5 x 7.3 mm 5 kV 1.2 x 50 µs Impulse Voltage 650 V 850 V Used with TBU® HSP Series TBU-CA065 TBU-CA085 The 2030 T-Series is a three element GDT that provides superior protection against fast rising voltage transients. GDTs on the market today commonly specify their impulse limiting performance at a 1k v/µs rate of rise. The T-series specifies its impulse limiting performance at a very fast 5 kV, 1.2 x 50 µs making it ideally suited for use with the TBU® HSP. The 2030 T-Series and TBU® HSP provide a superior protection solution for a broad number of industrial applications as well as telecom applications requiring GR-1089 or ITU-T K.21 compliance. These GDT devices provide coordinated overvoltage protection for the specified TBU® HSP protector models shown in the above table. Together, the GDT and TBU® High-Speed Protectors ~ Continued on page 2 ~ Features ■ ■ ■ ■ ■ ■ ■ Size: 5 mm diameter, 7.3 mm length Very fast acting Small size Stable breakdown throughout life Designed to operate with TBU® devices RoHS compliant* versions available UL Recognized Applications ■ ■ ■ Telecommunications Industrial electronics Avionics *RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011.

When exposed to a transient event, the TBU® HSP 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® HSP from overvoltage and shunting the excess surge energy to ground. Once the transient subsides, the GDT and TBU® HSP will reset to their normal off-state modes of operation. The new models are available as RoHS compliant.
