Abstract

An electrostatic discharge (ESD) protection device is disclosed including at least an NPN transistor and a PNP transistor coupled between a first node and a second node, wherein the ESD protection device may be configured to sink current from the first node to the second node in response to an ESD event. The transistors may be coupled such that a collector of the NPN may be coupled to the first node. A collector of the PNP may be coupled to the second node. A base of the NPN may be coupled to the emitter of the PNP. An emitter of the NPN may be coupled to a base of the PNP.
