SMD part sucks heat from hot spots

Vishay has released a series of surface-mount thermal jumper chip that transfer heat from electrically isolated components by providing a thermal conductive pathway to a ground plane or common heatsink. Called THJP and branded ThermaWick, they have an aluminium nitride substrate with 170W/mK thermal conductivity. By pulling heat across the electrical isolation barrier, they reduce the temperature ...
