Abstract
A transient-voltage-suppression protection device and a manufacturing process therefor, and an electronic product. The transient-voltage-suppression protection device includes a substrate, a first trap, a second trap, a first injection region, and a second injection region, where the first trap and the second trap are sequentially arranged on the substrate from left to right at an interval, have a same doping type that is opposite to a doping type of the substrate, and are respectively provided with the first injection region and the second injection region with opposite doping types. The electronic product includes the transient-voltage-suppression protection device. In the solutions described, protection can be triggered and started at a lower voltage; the capacitance is small, and the manufacturing process is simple.
