Abstract
An initiator with electrostatic discharge protection includes a generally cup-shaped housing having an open end, a quantity of pyrotechnic material in the housing, and a seal for closing the housing open end and encapsulating the pyrotechnic material within the housing. A pair of electrodes in contact with the pyrotechnic material extend through the seal. A zener diode is coupled in electrical circuit between the housing and one of the electrodes to provide a path for electrostatic discharge and to prevent electrostatic discharge from affecting the pyrotechnic material.
