I have a SOT-23 SMD transistor marked "2.X L" as shown in the image.
I managed to find out that "2X" stands for 2N4401 and the dot seems to mean "lead free". But I couldn't find the meaning of the perpendicular "L". I think it could be a "date code" but I'm not sure and I don't know either what its purpose is (e.g. does it affect the pinout?). I would appreciate any help.
Regards
