Made by Onsemi on a power supply board.
Hello amdkt7,
Welcome to the DigiKey TechForum.
I believe this part is BSP16T1-ND, which is obsolete.
If you are looking for the marking information or specifications, there is a datasheet on our website for this part.
Thank you! I think that is right! I do wonder how you were able to find it. Experience?
