Abstract
Electrostatic discharge (ESD) elements facilitate protection of electronic components from ESD events. The ESD element includes a pair of spark gaps between a first side and second side of the ESD element. The first side of the ESD element includes a peaked portion and a substantially planar portion. The second side of the ESD element includes a peaked portion opposite the substantially planar portion of the first side and a substantially planar portion opposite the peaked portion of the first side. This asymmetry facilitates use of peaked emitters regardless of the polarity of the charge applied to the ESD element while further facilitating the use of more optimized receiver surfaces opposite the emitters.
