WIPO Patent Application WO/2017/118028
Kind Code:
A1
Abstract:
A surge protector device comprises: an N-type substrate having a rear P-well layer over the entirety of a rear surface thereof and a front P-well layer on a front surface of the N-type substrate, wherein a side of the front P-well layer is provided with N+ implant regions. A TVS and a TSS are integrated, such that the device displays TVS characteristics when subjected to a forward surge, and displays TSS characteristics when subjected to a reverse surge, thus solving the problem in applications in which a TVS and a TSS connected in series are required to be employed. The surge protector device has a high level of integration and a low product cost, facilitates connection to an external circuit, and can be easily and conveniently applied.
