Overview
The BAS40W is a schottky Diode made by Nexperia in a SOT-323-3 package with 3 pins. 1 Independent 10uA@40V 120mA 1V@40mA 200mA 40V SOT-323-3 Schottky Diodes ROHS.
PCBKit's library has its KiCad symbol (tinkerforge:BAS40, from Tinkerforge) and its footprint (Package_TO_SOT_SMD:SOT-323_SC-70, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C549238).

Is there a KiCad symbol and footprint for the BAS40W?
Yes. The symbol is tinkerforge:BAS40 and the footprint Package_TO_SOT_SMD:SOT-323_SC-70, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAS40W?
SOT-323-3, with 3 pins. Its footprint is drawn on this page.
Where is the BAS40W datasheet?
Nexperia publishes it: the Datasheet link on this page opens it.
Where can I order the BAS40W?
JLCPCB lists it as part C549238, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BAS40W?
Parts like it in the library: the BAT54SWFILM by STMicroelectronics, the SMMBD770 by onsemi, the BAV70WG by Shandong Jingdao Microelectronics and the BAV99WG by Shandong Jingdao Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
