Abstract
An ESD protective triggering circuit for a triggering circuit for a solid state ESD protective device. The arrangement is to provide a controlled current to the protective device that triggers the device so that the device snaps-back and additionally the triggering device enables the parasitic transistor to participate in the draining of the ESD current. The triggering circuit also terminates the current to the protective device when the ESD voltage starts to fall. The triggering circuit can be used in any computer controlled electronics system.
