Abstract
Various embodiments provide an electrostatic discharge (ESD) protection device. The ESD protection device may include a subcollector, collector, base, and emitter formed in layers on top of one another. The emitter may include a different semiconductor than a semiconductor included in the base to form a heterojunction. The ESD protection device may include a collector contact disposed on the subcollector and an emitter contact disposed on the emitter. The ESD protection device may be a two-terminal device, with no conductive base contact coupled with the base.
