Diode markings identification?

[AUDIO FREQ]

I have 2 small diodes with different markings and I cannot find any info on them online. Or maybe I am just typing it in wrong in google. Both of them have small markings, 2 rows.

1st Diode:
Row1: A2
Row 2: 5

2nd Diode:
Row1: B1
Row 2: 7

Case type (and/or photos thereof) would be good to know. There are cases where the same marking denotes two (or more) VERY different parts, depending on the case.

Hey Khron, they are through hole diodes. They look like this

Can you show a schematic where they're used, or at least a photo of the board?

Or ar these just something you found in your parts bin? If this latter is the case, i'd just junk them. Whatever they are, new ones can be had for (worst case) cents per piece...

Yeah just some spare parts i had in my diode bin. I guess i'll just toss them. Thanks again Khron
