Abstract

A snubber circuit includes a snubber substrate including an electrically insulating carrier and an electrically conducting structured layer applied thereon, the electrically conducting structured layer including two segments. The snubber circuit further includes two electrically resistive layers, each resistive layer being applied onto the two segments of the electrically conducting structured layer of the snubber substrate, and a capacitor disposed on the electrically resistive layers and having two terminals, each terminal being electrically connected to one of the electrically resistive layers. Further, a power semiconductor module having such a snubber circuit is disclosed.
