Various embodiments of the present disclosure are directed towards an integrated chip. The integrated chip includes a first well region, a second well region, and a third well region disposed within a semiconductor substrate. The second well region is disposed between the first and second well regions. A first source/drain region is in the first well region. A second source/drain region is in the second well region. A gate structure is on the semiconductor substrate and spaced laterally between the first and second source/drain regions. A contact region is disposed in the third well region. A conductive structure is on the semiconductor substrate and spaced laterally between the second source/drain region and the contact region.

A semiconductor device may include a Silicon on Insulator (SOI) substrate, and a diode formed on the SOI substrate, the diode including a cathode region and an anode region. The semiconductor device may include at least one breakdown voltage trench disposed at an edge of the cathode region, and between the cathode region and the anode region.
