Questions

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?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the BAV21W?

JLCPCB lists it as part C3024449, with 2,624 in stock; the sellers' links on this page open their listings.

What can replace the BAV21W?

Parts like it in the library: the BAV21WS by hongjiacheng, the BAV21W by MDD, the BAV21WS by Jiangsu Changjing Electronics Technology (CJ) and the BAV21W by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
