Questions

Is there a KiCad symbol and footprint for the SM24?

Yes. 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 SM24?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the SM24 datasheet?

UMW publishes it: the Datasheet link on this page opens it.

Where can I order the SM24?

JLCPCB lists it as part C2833284, with 570 in stock; the sellers' links on this page open their listings.

What can replace the SM24?

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.
