Is there a KiCad symbol and footprint for the BAS40W-04?
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-04?
SOT-323, with 3 pins. Its footprint is drawn on this page.
Where is the BAS40W-04 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the BAS40W-04?
JLCPCB lists it as part C77293, with 2,725 in stock; the sellers' links on this page open their listings.
What can replace the BAS40W-04?
Parts like it in the library: the 1SS300(TE85L,F) by Toshiba, the BAT54SWFILM by STMicroelectronics, the SMMBD770 by onsemi and the BAV70WG by Shandong Jingdao Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
