Is there a KiCad symbol and footprint for the SM24QC?
Yes. The symbol is EasyEDA_Cloud:ASM712 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SM24QC?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SM24QC datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the SM24QC?
JLCPCB lists it as part C502601, with 3,146 in stock; the sellers' links on this page open their listings.
What can replace the SM24QC?
Parts like it in the library: the PESD1CAN by Nexperia, the NUP2105L by onsemi, the SZNUP2105L by onsemi and the NUP2105L by DOWO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
