2031-xxT-SM Series
2-Pole Gas Discharge Tube

Bourns® 2031T-xxT-SM Series 2-Pole Gas Discharge Tubes are designed for use with Bourns TBU® High-Speed Protectors to provide an ideal protection solution for industrial applications including telecommunications, industrial electronics, and avionics. These GDT devices provide coordinated overvoltage protection for TBU® High-Speed Protector models TBU-CA050-500-WH , TBU-CA065-100-WH , and TBU-CA085-200-WH . Together, they provide extremely fast overcurrent protection and overvoltage protection against electrical transients - in less than 1µs at the rated current. The 2031T-xxT-SM Series 2-Pole Gas Discharge Tubes can transition into conduction at a voltage below its maximum impulse rating, protecting the TBU® device from overvoltage and shunting the surge energy to ground.
