Good afternoon. Help identify a pair of SMD diodes by marking.

1) 7.5mm*4.0mm*2.0mm (l*w*h)
Marking:
3FJ
10
Voltage drop ~0.21V

2) 4.9mm*2.5mm*1.2mm (l*w*h)
Marking:
V6
29
Voltage drop ~ 0.61V

sometimes this can be a problem :(
divorced offices that stamp it is not known what, under only their own well-known markings.
Evaluation of the scheme helps (if this is not a number = you can still understand something,
but in a figure, without firewood / firmware = you will not understand anything,
and it is unlikely that anyone will provide it to you) /
repair = replacement from a similar device
