# Need help identifying SMD diodes

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.

• Just a note, alphabetic case often matters in SMD codes; s1y could be different from S1Y, S1y, etc. And would you believe, there is a 0O and O0 marking, being (different voltage!) zener diodes. What a mess. Feb 22, 2022 at 15:28
