Is there a KiCad symbol and footprint for the LL4448?
Yes. The symbol is Diode:LL4448 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 LL4448?
LL-34, with 2 pins. Its footprint is drawn on this page.
Where is the LL4448 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the LL4448?
JLCPCB lists it as part C84056, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LL4448?
Parts like it in the library: the LL4148 by MDD, the LL4148PF by STMicroelectronics, the LL4148-GS08 by Vishay Intertechnology and the LL4148 by YONGYUTAI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
