Is there a KiCad symbol and footprint for the B1040W?
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 B1040W?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the B1040W datasheet?
GP publishes it: the Datasheet link on this page opens it.
Where can I order the B1040W?
JLCPCB lists it as part C499639, with 0 in stock; the sellers' links on this page open their listings.
What can replace the B1040W?
Parts like it in the library: the B5819W by HT, the B5819W by FMS, the DSU24 by FMS and the B5819WHG by Galaxy Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
