Could someone help me to find product names of these diodes.
The search did not give clear results.
One of them is marked as s1y
And second is seems 05 with rotated J and it has dot under 05.
Thanks in advance!

The ones at the top are 1N4148s, the others at the bottom might be 5V1 zeners.

1\$\begingroup\$ Thanks Rohat! Seems that s1y is indeed 1N4148s. Not really sure about 5V1 zener, at least I don't see any related marking code in the data sheet. How did you identify this component? \$\endgroup\$– KirillFeb 22, 2022 at 13:56

2\$\begingroup\$ @KirillMonocle Take a look at here. To me, the marking of the diodes at the bottom looks like D5, not 05 (And also the s-manuals list does not contain any diodes under 05). Check p.2 from the datasheet I linked and you'll see that D5 is for 5V1 Zener. \$\endgroup\$ Feb 22, 2022 at 14:05

\$\begingroup\$ Thank you for the clarification, that's makes sense. This is definitely D5. \$\endgroup\$– KirillFeb 22, 2022 at 14:10
s1ycould be different fromS1Y,S1y, etc. And would you believe, there is a0OandO0marking, being (different voltage!) zener diodes. What a mess. \$\endgroup\$
