DBC type structure, comprising an insulating support () coated with at least one conductive zone () able to receive an electronic device, the conductive zone () being in contact with the support (), the insulating support incorporating means for thermal smoothing of the heat peak released by the component, these means comprising a cavity filled with a phase change material.

DBC structure using a support incorporating a phase change material

An electronic device includes an electronic component and a protective shield including a phase change material having a phase change temperature of between 20&#xb0; C. and 90&#xb0; C., an antivibration gel having hyperelastic and/or viscoelastic behavior at 20&#xb0; C., and a separation barrier positioned so as to separate the phase change material and the antivibration gel. The antivibration gel is positioned, at least partly, in contact with the electronic component, and has a thermal conductivity of greater than 1 W/m&#xb7;K at 20&#xb0; C.
