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 specifi cations are:

 

Part Number 2030-23T
DCBD 185 V
Size 5 x 7.3 mm
5 kV 1.2 x 50 μs Impulse Voltage 650 V
Used with TBU® HSP Series TBU-CA065

 

Part Number 2030-42T
DCBD 360 V
Size 5 x 7.3 mm
5 kV 1.2 x 50 μs Impulse Voltage 850 V
Used with TBU® HSP Series 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 specifi es its impulse limiting performance at a very fast 5 kV, 1.2 x50 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 specifi ed TBU® HSP protector models shown in the above table. Together, the GDT and TBU® High-Speed Protectors provide extremely fast overcurrent protection (OCP) and overvoltage protection (OVP) against electrical transients. When exposed to a transient event, the TBU® HSP will transition into a currentblocking 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*. The product data sheets with detailed specifi cations can be viewed on the Bourns website at www.bourns.com. Please contact your local Bourns Representative or Bourns Customer Service for samples or for further information.
