Overview
The BAS21 is a switching Diode made by HT in a SOT-23 package with 3 pins. 1.25V@200mA 100nA@200V 200mA 250V 50ns Independent SOT-23 Switching Diodes ROHS.
PCBKit's library has its KiCad symbol (Diode:BAS21, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C692842).

Is there a KiCad symbol and footprint for the BAS21?
Yes. The symbol is Diode:BAS21 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 BAS21?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BAS21 datasheet?
HT publishes it: the Datasheet link on this page opens it.
Where can I order the BAS21?
JLCPCB lists it as part C692842, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BAS21?
Parts like it in the library: the BAS21S-TP by Micro Commercial Components, the BAS21-JS by ZRE, the BAS21A-JS2 by ZRE and the BAS21C-JS3 by ZRE. Check their datasheets: a part that fits the footprint may still differ in its ratings.
