Abstract
A packaged semiconductor device comprising a package and a semiconductor device is described. The semiconductor device comprises a first and a second GND-pad bonded to one or more GND-pins with a first and a second bond wire respectively, a first functional pad bonded to a first functional pin with a third bond wire, a semiconductor layer of a P-type conductivity, a first semiconductor component and a second semiconductor component. The first semiconductor component is arranged to, when a transient current is applied to the first functional pin, divert at least part of the transient current to the first GND-pad from the first P-region to the first GND-pad via at least a first PN-junction. The second semiconductor component comprises a second N-type region of a terminal of the second semiconductor component associated with the first functional pad. The first GND-pad is in contact with a second P-type region. The second GND-pad is in contact with a third N-type region. At least part of the second P-type region is arranged in between the first semiconductor component and the second semiconductor component, and at least part of the third N-type region is arranged in between the at leas…
