Is there a KiCad symbol and footprint for the BAT43W?
Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAT43W?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the BAT43W datasheet?
Galaxy Microelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BAT43W?
JLCPCB lists it as part C21882535, with 1,460 in stock; the sellers' links on this page open their listings.
What can replace the BAT43W?
Parts like it in the library: the B5819W by MDD, the B5819W by hongjiacheng, the B5819W by HXY MOSFET and the SD103AW by HXY MOSFET. Check their datasheets: a part that fits the footprint may still differ in its ratings.
