Please identify this SMD part SOT23-6 with top marking 010 and bottom marking 1318 as shown in attached photo. I have tried my best in search but without success, appreciate if you tell me how you were able to find it.

SOT23-6 Top Marking 010

  • \$\begingroup\$ Muthanna A. Alwahash - Hi, (a) I changed your request from "can someone help me..." since that is just a yes/no answer. However it's obvious that you want to identify the component, so I've changed the question to say that. (b) Identification questions here are usually about components on PCBs etc. where we can get context about the component from the surrounding circuit. That isn't possible when you only show the component :( Do you have any other information about this component or its function? If so, please edit the question to add it. Thanks. \$\endgroup\$

  • \$\begingroup\$ Unfortunately I don't have any other context that I can add, components are new not from a PCB I got it in one of my 5 years old orders along with many other components and now I can't identify it. \$\endgroup\$ Oct 29, 2023 at 15:13

Not confirmed but it could be FDG6301N. Based on the linked datasheet, the marking scheme is 01M where M is some date code:

    \$\begingroup\$ No it is not, marking on FDG6301N is .21 as mentioned in its datasheet \$\endgroup\$ Oct 28, 2023 at 17:46

    \$\begingroup\$ Then please delete your answer, if you feel that it isn't correct. \$\endgroup\$ Oct 28, 2023 at 17:50

    \$\begingroup\$ Well the datasheet is a bit confusing about markings. onsemi.com/pdf/datasheet/fdg6301n-d.pdf "01M" ( 01 = Specific Device Code M = Assembly Operation Month) and on page 6 "XXXM" (XXX = Specific Device Code M = Date Code*) \$\endgroup\$

    \$\begingroup\$ FDG6301N package type is SC-88 and what I have is SOT23-6. I don't think this answer is correct. \$\endgroup\$ Oct 29, 2023 at 15:19
