The Triggered Vacuum Spark Gaps are ideal high-voltage switches for applications where a wide operating voltage range is desired. The low end of the operating voltage range is independent of the Static Breakdown Voltage (SBV). Operating ranges from 300 volts to 80 kilovolts are possible. Switching times (from the trigger input to the start of main gap current flow) of less than 1 microsecond may be achieved when using a suitable trigger. These switches are commonly used in “crowbar” circuits for protection against overvoltage conditions.
