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. FEATURES APPLICATIONS ■ Tight self-breakdown voltage tolerance (±10%;TA & TB series) ■ Adjustable self-breakdown voltage (TG-221 to TG-226) ■ Rugged ceramic-metal construction ■ Refractory metal electrodes ■ Corrosion-resistant stainless steel external surfaces (TB series) ■ ■ ■ ■ High current surge generators Exploding bridge wire systems Crowbars Flashtube triggers STANDARD VOLTAGES Series or P/N Self-Breakdown Units Voltage (typ) TA 1.0 2.0 5.0 7.0 10.0 15.0 kV kV kV kV kV kV TB 2.5 5.0 10.0 15.0 20.0 25.0 kV kV kV kV kV kV 1.0-20.0 18.0-40.0 1.0-20.0 18.0-40.0 35.0-60.0 kV kV kV kV kV TG-221 TG-222 TG-224 TG-225 TG-226 North America: 1-800-CPCLARE 558 Europe: 32-11-300868 Asia: 886-2-2523-6368 Japan: 81-3-3980-2212 HIGH-ENERGY TRIGGERED SPARK GAPS Triggergaps SPECIFICATIONS All characteristics at 25˚C PARAMETER TA-1.0 CONDITIONS SYMBOL MIN TA-2.0 TYP MAX MIN TYP TA-5.0 MAX MIN TYP MAX UNITS Device Specifications Self-Breakdown Voltage Applied Voltage Trigger Voltage1 Dimension A Life Ratings 100V/s t r=0.5µs, PW=3.0µs Discharge Life2 ≥1000 shots into .2Ω PARAMETER CONDITIONS EZ Ebb etrig - 0.9 1.0 1.1 1.8 2.0 2.2 4.5 5.0 5.5 kV 0.4 0.85 0.7 1.7 1.2 4.2 kV 3.0 2.5 3.0 2.5 3.5 2.5 kV pk 0.687 0.750 0.813 0.697 0.760 0.823 0.697 0.760 0.823 inches 45 - - 50 - MAX MIN TA-7.0 SYMBOL MIN TYP - 50 - MAX MIN TA-10.0 TYP - J TA-15.0 TYP MAX UNITS Device Specifications Self-Breakdown Voltage Applied Voltage Trigger Voltage1 Dimension A Life Ratings 100V/s t r=0.5µs, PW=3.0µs Discharge Life2 ≥1000 shots into .2Ω PARAMETER CONDITIONS EZ Ebb etrig - 6.3 7.0 7.7 9.0 10.0 11.0 13.5 15.0 16.5 kV 1.9 5.8 3.5 8.5 7.0 12.5 kV 3.7 2.8 5 3.5 8.0 4.5 kV pk 0.697 0.760 0.823 0.727 0.790 0.853 0.767 0.830 0.893 inches 50 - - 60 - - 70 MAX MIN TYP MAX MIN TYP MAX UNITS 2.75 2.0 1.8 0.23 2.03 4.5 1.5 3.2 - 5.0 1.99 - 5.5 4.0 1.9 0.23 2.03 9.0 3.0 4.6 - 10.0 1.99 - 11.0 8.0 2.1 0.58 2.10 kV kV kV pk inches inches inches - 150 - - 300 - - J MAX MIN TYP MAX MIN TYP MAX UNITS 16.5 12.0 3.5 0.58 2.10 18.0 6.0 8.0 - 20.0 2.79 - 22.0 16.0 4.5 0.58 2.10 22.5 7.5 9.7 - 25.0 2.79 - 27.5 20.0 5.2 0.58 2.10 kV kV kV pk inches inches inches - 300 - - 300 - - J TB-2.5 SYMBOL MIN TYP TB-5.0 - - J TB-10.0 Device Specifications Self-Breakdown Voltage Applied Voltage Trigger Voltage1 Dimension A Dimension B Dimension C 100V/s t r=0.5µs, PW=3.0µs EZ Ebb etrig - Discharge Life2 discharges into .3Ω - PARAMETER CONDITIONS 2.25 2.50 0.8 3.1 1.99 - Life Ratings 150 - TB-15.0 SYMBOL MIN TYP TB-20.0 TB-25.0 Device Specifications Self-Breakdown Voltage Applied Voltage Trigger Voltage1 Dimension A Dimension B Dimension C 100V/s t r=0.5µs, PW=3.0µs EZ Ebb etrig - discharges into .3Ω - 13.5 15.0 4.5 6.3 2.67 - Life Ratings Discharge Life2 300 - 1 The trigger voltages given in these tables are the minimum triggering voltages necessary for triggering at the corresponding applied voltage limits. 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 PARAMETER CONDITIONS SYMBOL MIN TYP TG-222 TG-224 MAX MIN TYP MAX MIN TYP MAX UNITS Device Specifications Self-Breakdown Voltage Applied Voltage Dimension A Dimension B 100V/s EZ E bb - 1.0 0.5 - 2.25 2.50 20.0 18.0 - 18.0 15.0 - 3.25 2.50 40.0 35.0 - 1.0 0.5 - 3.00 4.50 20.0 19.0 - kV kV inches inches - 20 3000 - - 20 3000 - - 50 6000 - - kA J - Life Ratings Peak Current Discharge Life 3 PW=30µs 1000 shots into 1Ω PARAMETER CONDITIONS TG-225 SYMBOL MIN TYP TG-226 MAX MIN TYP MAX UNITS 40.0 35.0 - 35.0 30.0 - 4.50 4.50 60.0 55.0 - kV kV inches inches - 50 6000 - - kA J Device Specifications Self-Breakdown Voltage AppliedVoltage Dimension A Dimension B 100V/s EZ E bb - 18.0 15.0 3.50 4.50 - 50 6000 - Life Ratings Peak Current Discharge Life 3 PW=30µs 1000 shots into 1Ω - 1 The trigger voltages given in these tables are the minimum triggering voltages necessary for triggering at the corresponding applied voltage limits.
