Switching Spark Gaps (GDT)

Switching spark gaps are designed specifically for voltage controlled switching of capacitive discharge circuits where a high energy, low loss, fast rate of switching is required. These products are ideally suited for applications where a capacitive discharge is utilised with a transformer to obtain pulses of high-voltage levels in the order of several thousand volts. Utilised in gas heating and gas appliances along with protection of Xenon discharge lamps in both the architectural and automotive areas.
