WebGas discharge tube (GDT) Gas discharge tubes consist of two or more metal electrodes separated by a small gap and held by a ceramic or glass cylinder. The cylinder is filled with a noble gas mixture, which sparks over into a glow discharge and finally an arc condition when sufficient voltage is applied to the electrodes. WebDec 21, 2024 · A gas discharge tube (GDT) is a state machine which transitions from a high impedance ("normal") state to a low impedance ("glow") state when the potential across its terminals exceeds the spark-over voltage. Older SPICE models of GDTs tend to use switching circuitry.
