Gas discharge tube (GDT) typical application circuit
Ceramic gas discharge tubes (GDT) are widely used in communication
lines and power line protection of electronic products such as
communications, security, and industry. When used in power line
protection, ceramic gas discharge tubes (GDT) should
Applied in series with MOV or TVS, as shown in Figure 2. Figure 3
shows the RJ45 interface protection, Figure 4 and Figure 5 show the
RS485 interface and BNC respectively.
Two-level interface protection scheme, the first level uses ceramic
gas discharge tube.

Main characteristics of gas discharge tube
>DC breakdown voltage: 70~7500 V
>Impact discharge current (8/20 μs): maximum 100 kA
>Impact discharge current (10/350 μs): maximum 100 kA
>Power frequency discharge current (1 s): maximum 20 A
>Power frequency discharge current (0.2 s): maximum 300 A
>Arc voltage: 10~35 V
>Insulation resistance: minimum 1 GΩ
>Capacitance: 0.2 pF minimum
Characteristics of Ceramic Gas Discharge Tube (GDT)
> The junction capacitance is low, the junction capacitance of
most series products does not exceed 2pF, and the junction
capacitance of extra-large flow products is in the tens to tens of
picofarads;
> Large flow rate, our ceramic gas discharge tube (GDT) single
unit has a flow rate range of 8/20μs from 500A to 100kA;
> High insulation resistance, generally above 1GΩ, not easy to
age and has high reliability;
> DC breakdown voltage range is 75V~6000V, pulse breakdown
voltage range is 600V~7800V;
> Various packages, including SMD devices and plug-in devices,
two-terminal devices and three-terminal devices, to meet different
application needs;
> Easy to install;
