Abstract: An electronic circuit comprising a power transistor of the MOSFET type comprising a gate connected to a control circuit of the gate. The control circuit of the gate configured to operate at a temperature called ambient temperature, non-cryogenic. The power transistor as well as an interfacing circuit connected between said gate and said control circuit configured to operate at a cryogenic temperature. Each component of the interfacing circuit established at a maximum distance (L) from the power transistor. At least one measurement means configured to measure at least one measurement signal, representative of a junction temperature of the power transistor, is connected between the interfacing circuit operating at a cryogenic temperature and the control circuit operating at ambient temperature.

Abstract: An electronic component with a substrate connected a plurality of connection pins and on one face of which is affixed an electronic die fixing layer, and at least one electronic die assembled on said electronic die fixing layer. The electronic component includes a first heat exchanger and a layer of thermally conductive and electrically insulating material arranged in contact with said substrate. The first heat exchanger receives a circulating cryogenic fluid, and the electronic die, the electronic die fixing layer, the substrate, and the layer of thermally conductive and electrically insulating material as well as one end of each of said connection pins are enveloped in a volume of electrically insulating material at cryogenic temperature.
