DESCRIPTION
FEATURES
APPLICATIONS
CP Clare's Triggergaps are high-energy spark gaps that are capable of switching stored energy in a
fraction of a microsecond. Triggergaps use no standby power, are extremely rugged and require only a
low energy high voltage triggering pulse.

1
Unless otherwise noted, specifications are determined by testing in the circuit shown in figure 2.
2
The trigger voltages given in these tables are the minimum triggering voltages necessary for triggering at the corresponding
operating 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 (mode C, see figure 3) or applied across the
trigger electrode and opposite main electrodes (mode A, see figure 3)
3
Delay time is defined as the delay between the time the trigger voltage reaches the point of breakover and the time the arc in the
main gap begins conduction.
4
Product experiences a less than 10% reduction in self breakdown voltage after test.
