Is there a KiCad symbol and footprint for the LL4148?
Yes. The symbol is Diode:LL4148 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 LL4148?
SOD-80C, with 2 pins. Its footprint is drawn on this page.
Where is the LL4148 datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the LL4148?
JLCPCB lists it as part C212826, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LL4148?
