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.
