Is there a KiCad symbol and footprint for the FDLL4148?
Yes. The symbol is Device:D and the footprint Diode_SMD:D_MiniMELF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the FDLL4148?
SOD-80, with 2 pins. Its footprint is drawn on this page.
Where is the FDLL4148 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the FDLL4148?
JLCPCB lists it as part C78608, with 151,044 in stock; the sellers' links on this page open their listings.
What can replace the FDLL4148?
Parts like it in the library: the LL4148 by LGE, the LL4148 by onsemi, the LL4148 LL34 by TDSEMIC and the LL4148 by Yangzhou Yangjie Electronic Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the FDLL4148?
9 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
