Abstract

The component incorporates, in topological terms, a scalable number of triac structures in a concentric annular arrangement. The component can be used with an electronic device to protect against electrostatic discharges. For example, the components can be used to protect the input/output pad, the first power supply terminal, and the second power supply terminal of an integrated circuit against electrostatic discharges.
