Surface Mount 2-Electrode Gas Discharge Tube (GDT)

SC2E6-SMD Series

Description

Gas discharge Tubes (GDT) are classical components for

protecting the installations of the telecommunications. It is

essential that IT and telecommunications systems -with their

high-grade but sensitive electronic circuits - be protected by

arresters. They are thus fitted at the input of the power supply

system together with varistors and at the connection points to

telecommunication lines. They have become equally indispensable

for protecting base stations in mobile telephone systems as well as

extensive cable television (CATV) networks with their repeaters

and distribution systems.

These protective components are also indispensable in other

sectors, In AC power transmission systems, they are often used

with current-limiting varistors, In customer premises equipment

such as DSL modems, WLAN routers, TV sets and cable modems

In air-conditioning equipment, the integral black-box concept offers

graduated protection by combining arresters with varistors, PTC,

diodes and inductor.

Test Condition / Description

Requirement

DC Spark-over Voltage

The voltage is measured with a slowly rate of rise dv / dt=100V/s

Impulse Spark-over

Voltage

The maximum impulse spark-over voltage is measured with a rise time of

dv / dt=100V//μs or 1KV/μs

The resistance of gas tube shall be measured each terminal each other terminal,

please see above spec.

Insulation Resistance

The capacitance of gas tube shall be measured each terminal to each other

terminal.

Capacitance

Test frequency :1MHz

The maximum current applying a waveform of 8/20μs that can be applied across

the terminals of the gas tube. One hour after the test is completed, re-testing of the

DC spark-over voltage does not exceed ±30% of the nominal DC spark-over

voltage. Dwell time between pulses is 3 minutes.
