Bourns 2030-XXT-SM 3-Pole Miniature Gas Discharge Tube

Bourn 2030-XXT-SM Series 3-Pole Miniature Gas Discharge Tube (GDT) is designed to provide superior protection against fast rising voltage transients. With a very fast impulse limiting performance of 5kV, 1.2 x 50μs, the Bourns 2030-XXT-SM Series 3-Pole Miniature GDT is ideally suited for use with the TBU® High-Speed Protectors (HSP). Together, the 2030-XXT-SM Series 3-Pole GDT and TBU HSP offer extremely fast overcurrent protection (OCP) and overvoltage protection (OVP) against electrical transients.

When exposed to a transient event, TBU HSP transitions into a current-blocking condition in less than one microsecond at the rated current. When needed, the 2030-XXT-SM Series 3-Pole GDT transitions into conduction at a voltage below its maximum impulse rating, protecting the TBU HSP from overvoltage and shunting the excess surge energy to ground. After the transient subsides, 2030-XXT-SM Series 3-Pole GDT and TBU HSP will reset to their normal off-state modes of operation. Bourns 2030-XXT-SM Series Fast Acting 3-Pole Miniature Gas Discharge Tube and TBU HSP offer exceptional voltage protection for a wide range of industrial applications as well as telecom applications requiring GR-1089 or ITU-T K.21 compliance.
