Abstract
In an embodiment, a semiconductor die includes a transistor device that has a cell field and an edge termination region, a source pad arranged on the cell field, a gate pad laterally arranged laterally adjacent the cell field and in the edge termination region, a shielding region laterally surrounding the cell field, the shielding region including a non-depletable doped. The polysilicon ESD protection diode is arranged laterally between the gate pad and the source pad and vertically above at least a portion of the shielding region, and includes at least two separate sections that are electrically coupled in parallel between the gate pad and the source pad. The sections are laterally spaced apart by a gap situated at a corner of the gate pad.
