Abstract:
1. A semiconductor component comprising: a semiconductor body; plural vertically displaced metallization planes supported on the semiconductor body including at least a first metallization plane and a second metallization plane, the first metallization plane including a first planar winding of a first transformer, the second metallization plane including a second planar winding of the first transformer, the second metallization plane arranged between the semiconductor body and the first metallization plane; a protective ring surrounding the first transformer in the lateral direction of the semiconductor body, the protective ring having at least one first metal portion and at least one further metal portion, the metal portions being electrically conductively connected to one another, the first metal portion arranged in the first metallization plane and at least one further metal portion arranged in at least one further metallization plane; and a passivation layer arranged on a metallization plane which is furthest apart from the semiconductor body in the vertical direction; wherein a metal portion which is furthest apart from the semiconductor body in the vertical direction is further apart from the first planar winding in a lateral direction component than a metal portion which is closest, in the vertical direction of the semiconductor body, to the metal portion which is further apart in the lateral direction component from the first planar winding.
