Is there a KiCad symbol and footprint for the BAS40X?
Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_SOD-523, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAS40X?
SOD-523(SC-79), with 2 pins. Its footprint is drawn on this page.
Where is the BAS40X datasheet?
Yangzhou Yangjie Electronic Technology publishes it: the Datasheet link on this page opens it.
Where can I order the BAS40X?
JLCPCB lists it as part C968039, with 8,034 in stock; the sellers' links on this page open their listings.
What can replace the BAS40X?
Parts like it in the library: the BAS516-QX by Nexperia, the B5819WT by hongjiacheng, the SD103AWT by hongjiacheng and the B5819WT by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
