Structures for an electrostatic discharge device including a silicon-controlled rectifier and methods of forming a structure for an electrostatic discharge device that includes a silicon-controlled rectifier. The structure includes a first well in a semiconductor substrate, a second well and a third well in the first well, and a fourth well in the first well. The first well has a first conductivity type, and the second well and the third well have the first conductivity type. The fourth well positioned in a lateral direction between the second well and the third well, and the fourth well has a second conductivity type opposite to the first conductivity type. The second well, the third well, and the fourth well are positioned in a vertical direction between the first well and a top surface of the semiconductor substrate.
