A Method of Anti-electrostatic Discharge for Semiconductor Bridge Initiators

In order to enhance the capacity of anti-electrostatic discharge between pole and case of semiconductor bridge initiators, the transient voltage suppressor(TVS) which has the characteristic of transient voltage suppression was used to avoid electrostatic discharge between pole and case of SCB initiators. The static discharge test show that most of the current passed from the TVS when the electrostatic discharged, and the SCB didn't fire. The TVS can effectively prevent the SCB from electrostatic discharge between the pole and case.
