Surface Mount 2-Electrode Gas Discharge Tube (GDT)
UN1206 Series
Electrical Rating
Item
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
Capacitance
The capacitance of gas tube shall be measured each terminal to each other
terminal.
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 ±40% of the nominal DC spark-over
voltage. Dwell time between pulses is 3 minutes.
