The thermal pad of SN65HVD78 VSON(8) package

Other Parts Discussed in Thread: SN65HVD78


SN65HVD78 VSON(8) package has a thermal pad. Should it be grounded or left float?


  • Hi Wenwei,

    Either approach is OK. The pad is not electrically connected to the die; it is just present to aid in thermal conduction. We do recommend that it be connected to a copper plane on the PCB, though, and typically the ground plane is the most convenient choice.

    Best regards,
