Is there a KiCad symbol and footprint for the BAV21W?
Yes. The symbol is Diode:BAV21 and the footprint Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAV21W?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the BAV21W datasheet?
ElecSuper publishes it: the Datasheet link on this page opens it.
Where can I order the BAV21W?
JLCPCB lists it as part C5249629, with 157 in stock; the sellers' links on this page open their listings.
What can replace the BAV21W?
Parts like it in the library: the BAV21W by MDD, the BAV21W by Shandong Jingdao Microelectronics, the BAV21WS by MDD and the BAV21W by Wild Goose. Check their datasheets: a part that fits the footprint may still differ in its ratings.
