HIGH-ENERGY TRIGGERED SPARK GAPS Triggergaps DESCRIPTION CP Clare's Triggergaps are high-energy spark gaps that are capable of switching stored energy in a fraction of a microsecond. Triggergaps require no standby power, are extremely rugged, and require only a low-energy, highvoltage triggering pulse. The miniature TA series (1-15kV) provides switching capability for pulses with energy content as high as 50 joules. The larger TB series (2.5-25 kV) will reliably switch pulses with up to 300 joules of energy. The TG-221 to 226 (1-60 kV) can switch pulses with energy contents of up to 6000 joules and feature adjustable self-breakdown voltages.

As the applied trigger voltage increases, the trigger voltage required for triggering decreases. It is assumed that the trigger is applied across the trigger and adjacent main electrodes — higher trigger voltages are required if it is applied across the trigger voltage and opposite main electrodes. 2 End point for life testing is a 15% reduction in the self-breakdown voltage. 3 Because the self-breakdown voltage of these devices is adjustable, the trigger voltage required for any particular applied voltage cannot be specified. Clare suggests setting the selfbreakdown voltage to at least 115% of the maximum applied voltage. www.cpclare.com 559 HIGH-ENERGY TRIGGERED SPARK GAPS Triggergaps SPECIFICATIONS All characteristics at 25˚C TG-221 CONDITIONS 100V/s TG-222 TYP 3.25 2.50 - TG-224 TYP 3.00 4.50 - PARAMETER Device Specifications Self-Breakdown Voltage Applied Voltage Dimension A Dimension B SYMBOL MIN TYP EZ E bb - MAX MIN 20.0 18.0 18.0 15.0 20 3000 MAX MIN 40.0 35.0 1.0 0.5 50 6000 MAX UNITS 20.0 19.0 kV kV inches inches kA J PW=30µs 1000 shots into 1Ω - 1.0 0.5 20 3000 2.25 2.50 - Life Ratings Peak Current Discharge Life 3 TG-225 PARAMETER Device Specifications Self-Breakdown Voltage AppliedVoltage Dimension A Dimension B 100V/s EZ E bb - TG-226 TYP 4.50 4.50 - CONDITIONS SYMBOL MIN TYP 18.0 15.0 3.50 4.50 50 6000 - MAX MIN 40.0 35.0 35.0 30.0 50 6000 MAX 60.0 55.0 - UNITS kV kV inches inches kA J PW=30µs 1000 shots into 1Ω - Life Ratings Peak Current Discharge Life 3 1 The trigger voltages given in these tables are the minimum triggering voltages necessary for triggering at the corresponding applied voltage limits.
