Abstract
In an ESD protection device making use of a LVTSCR, at least one contacted drain and at least one emitter are formed, and are arranged laterally next to each other to be substantially equidistant from the gate of the LVTSCR, to improve holding voltage and decrease size. The ratio of emitter width to contacted drain width is adjusted to achieve the desired characteristics.
