GDT Operation Of The Ceramic Gas Discharge Tube GDT 8TL230M

GDT surge arrestor devices are designed to operate on the gas-physical principle of the highly effective arc discharge. Essentially a voltage dependent switch, the GDT maintains a high impedance off-state until a voltage exceeds the device’s sparkover voltage. At this point, the gas in the GDT becomes fully ionized and conduction takes place within a fraction of microsecond. During arc-over, the GDT exhibits the low impedance of a crowbar device resulting in very low on-state voltage (arc voltage). The crowbar effect of the GDT effectively limits the overvoltage to a low level and shunts the associated follow current away from downstream components and circuitry. When the surge event subsides and the system voltage returns to normal levels, the GDT will reset into its high impedance (off) state.

This product is suitable for communication equipments and other electronic equipments for transient over-voltage protection against high voltage and lightning damage.

GDT Types Of The Ceramic Gas Discharge Tube GDT 8TL230M

Ampfort offers a broad range of 2-electrode and 3-electrode GDT devices (figures 2 & 3). 2-Electrode devices are typically used to provide line to ground or line to line protection (1 to 2). In a single device, a 3-electrode GDT can provide protection from line to line (1-2) as well as line to ground (1 to 3, 2 to 3) in a single device. Standard GDTs (75 to 600 V) are provided in both 2- and 3-electrode devices. High voltage GDTs (800 to 7200 V) are primarily offered in 2-electrode devices and some select 3-electrode packages. In addition, specialized GDTs are offered in high current, fast acting, hybrid and FLAT technology versions allowing the customer to address a wider array of protection needs.
