Is there a KiCad symbol and footprint for the SD24?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-323, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SD24?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the SD24 datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the SD24?
JLCPCB lists it as part C502530, with 2,547 in stock; the sellers' links on this page open their listings.
What can replace the SD24?
Parts like it in the library: the PESD1LIN by UMW, the H24VND3BA by hongjiacheng, the PESD24VL1BA by GOODWORK and the PESD24VS1UA by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
