My drone's power distribution board heated up.

There is a diode in the picture - I could not identify it.

Can anyone help?

It appears to be a 1SMB51AT3 TVS diode rated for 51V with a current rating of 7.3 amperes.

The housing size and shape match, as well as the position of the codes as seen in the linked datasheet.
