Hofstra Group Triggered Spark Gaps are used by pulsed power scientists who need to control GigaWatts of electricity. Like a FET, the triggered Triggered Spark Gap is voltage-controlled, and, like an SCR, it is a bistable device that can be turned on, but not off. Our Triggered Spark Gaps operate by using voltage to ignite a plasma between two terminals, which enables conduction. Once the current in the circuit drops, the plasma extinguishes, and the Triggered Spark Gap recovers to its original high-impedance state.
