摘要: An electrostatic discharge (ESD) protection device includes a semiconductor substrate, a base region in the semiconductor substrate and having a first conductivity type, an emitter region in the base region and having a second conductivity type, a collector region in the semiconductor substrate, spaced from the base region, and having the second conductivity type, a breakdown trigger region having the second conductivity type, disposed laterally between the base region and the collector region to define a junction across which breakdown occurs to trigger the ESD protection device to shunt ESD discharge current, and a gate structure supported by the semiconductor substrate over the breakdown trigger region and electrically tied to the base region and the emitter region. The lateral width of the breakdown trigger region is configured to establish a voltage level at which the breakdown occurs.
