Overview
The BAT42W is a schottky Diode made by Diodes Incorporated in a SOD-123 package with 2 pins. -55℃~+125℃ 1 Independent 1V@0.2A 200mA 30V 4A 500nA@25V SOD-123 Schottky Diodes ROHS.
PCBKit's library has its KiCad symbol (Diode:BAT42, from KiCad's library) and its footprint (Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal, from KiCad's library), ready for a KiCad board. 12,363 are in stock at JLCPCB (part C134396). 5 open-source boards in 5 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the BAT42W?
Yes. The symbol is Diode:BAT42 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 BAT42W?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the BAT42W datasheet?
Diodes Incorporated publishes it: the Datasheet link on this page opens it.
Where can I order the BAT42W?
JLCPCB lists it as part C134396, with 12,363 in stock; the sellers' links on this page open their listings.
What can replace the BAT42W?
Parts like it in the library: the BAT41KFILM by STMicroelectronics, the BAT46WJ by Nexperia, the BAT43W by hongjiacheng and the BAT42WS by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BAT42W?
5 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
