Questions

Is there a KiCad symbol and footprint for the BAS21W?

Yes. The symbol is Diode:BAS21 and the footprint Package_TO_SOT_SMD:SOT-323_SC-70, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BAS21W?

SOT-323-3, with 3 pins. Its footprint is drawn on this page.

Where is the BAS21W datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the BAS21W?

JLCPCB lists it as part C44849, with 1,604 in stock; the sellers' links on this page open their listings.

What can replace the BAS21W?

Parts like it in the library: the BAS21SW by YFW, the BAS21AW by STMicroelectronics, the BAS21AW by Nexperia and the BAS21W by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
