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 self-
breakdown voltage to at least 115% of the maximum applied voltage.
