Is there a KiCad symbol and footprint for the BAS21-HF?
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 BAS21-HF?
SOT-23, with 5 pins. Its footprint is drawn on this page.
Where is the BAS21-HF datasheet?
Comchip publishes it: the Datasheet link on this page opens it.
Where can I order the BAS21-HF?
JLCPCB lists it as part C17670573, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BAS21-HF?
Parts like it in the library: the MMBD1503A by FUXINSEMI, the BAS21C by Guangdong Hottech, the BAS21S by Guangdong Hottech and the BAS21 by Doeshare. Check their datasheets: a part that fits the footprint may still differ in its ratings.
