    Napoleon (Blownaparte)!

    By the look of that board - it probably doesn't matter much what that component used to be.

    Eeny, meeny, miny, moe... that sure doesn't look like a diode-do!...

    Seriously, there's really no way to tell for sure from the picture... but if I had to make a bet, I'd probably lean towards its being a tantalum capacitor...

    Find a schematic or another, unexploded PCB to look at.

    Can you clean away some of that tasty char to read the reference designator?

    You could provide some more info, like what the PCB usually do, when it's not melting components. What type of equipments it is used in, and maybe a picture of the whole PCB. The PCB might have som marking and numbers on it, that can be used in a Google search. Could it be a malfunctioned fuse?

    Whatever that black & crispy thing was - sacrificed itself to save the fuse.
