Default Identifying smd diodes on Hifonics 2010d Driver board

I can't make out the codes on Perry's photo 100% and want to make sure I order the right diodes because I know the ones I have circled in red (D3, D6, D7) in Perry's photo are different than D1 and D2.
Just to be clear im looking for D3, D6, and D7.
My best guess is their marked J2 and the other 2 are A2?

That's what it looks like to me.

That's correct. The datasheet above 'MAY' give the correct codes but I've never confirmed that they're the right codes.

Thanks Perry, I don't know if this helps but on a good board there testing .762mv on diode test in and out of circuit. At first I thought they may be the same as d1 and d2 on that board but those are only .550 or so on diode out of circuit. For educational purposes I tried same diode in d3 but it trips the protection circuit in my power supply when the remote lead connection is made.

If you want to confirm that they're zener diodes, connect a relatively high value resistor (1k-4.7k) in series with the diode and connect the two across the 12v power supply. The zener will drop its value. You could compare that to the datasheet.

Confirmed that the two diodes in question match the linked datasheet. 5.06v and 8.27v measured voltage.

For the heck of it, if anyone stumbles upon this I found a good reference for testing zener diodes.
