Default Assistance identifying component on 820-3455-A IO board

I've been unable to source any schematics for this (820-3455-A) A1466 (Macbook Air 2013-2015) power/IO daughterboard, and I don't have a replacement on hand.

I've narrowed my issue down to this diode(?) marked in these images, right behind the MagSafe port, but it has a big blow-out crater in it. Could any of you help me identify this part, closely enough that I can source a replacement?

This might be a bit late but, if this is referring to the diode in the picture, it is D6904, a protection diode.
