<p>A power semiconductor component is used for boiling cooling of a power semiconductor crystal disc having two main electrodes, and optionally one or more control electrodes. Two multicontacts are provided, each being electrically connected to a respective one of the main electrodes for thermal and mechanical relief. Two heat sinks are provided, each being in electrical and thermal contact with a respective one of the multicontacts. Connecting eyes are integral with the heat sinks for electrically connecting the main electrodes. A liquid and gas-tight housing surrounds the semiconductor crystal disc, the housing including a ceramic sleeve having a boiling liquid space formed therein and metallic covers disposed laterally on the ceramic sleeve, the connecting eyes protrude through and are connected to the metallic covers, and an insulating sleeve is molded around the housing. The insulating sleeve has at least one stub formed thereon having a hole formed therein for conducting an electrically-insulating refrigerant flow through the housing directly contacting the semiconductor disc, the metallic covers have partially circular cutouts formed therein and the ceramic sleeve has a hole formed therein for the refrigerant flow.</p> |
