High Voltage 2-Electrode Gas Discharge Tube (GDT) UN2E5 Series Electrical Rating Item Test Condition / Description DC Spark-over Voltage Impulse Spark-over Voltage The voltage is measured with a slowly rate of rise dv / dt=100V/s The maximum impulse spark-over voltage is measured with a rise time of dv / dt=100V//μs or 1KV/μs Insulation Resistance Capacitance Requirement The resistance of gas tube shall be measured each terminal each other terminal, please see above spec. 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 ±30% of the nominal DC spark-over voltage. Dwell time between pulses is 3 minutes.
