The disclosed technology generally relates to electrostatic discharge protection devices that protect circuits from transient electrical events and more particularly to low-voltage triggered silicon-controlled rectifier devices implemented using a bulk fin field-effect transistor technology. In one aspect, an electrostatic discharge protection device comprises a low-voltage triggered silicon-controlled rectifier having an embedded grounded-gate n-channel metal oxide semiconductor structure implemented as a bulk fin field-effect transistor having a plurality of fin structures. The fin structures direct current from an avalanche zone to a gate formed over the fin structure. The electrostatic discharge protection device has a higher trigger current and a lower leakage current than a similar device having a planar embedded grounded-gate n-channel metal oxide semiconductor structure because the current flow is restricted by the fin structures.
