Is there a KiCad symbol and footprint for the BAV19W?
Yes. The symbol is Diode:BAV19 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 BAV19W?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the BAV19W datasheet?
Diodes Incorporated publishes it: the Datasheet link on this page opens it.
Where can I order the BAV19W?
JLCPCB lists it as part C5245010, with 25 in stock; the sellers' links on this page open their listings.
What can replace the BAV19W?
Parts like it in the library: the BAV21WS by hongjiacheng, the BAV21W by MDD, the 1N4148WL(T4) by Shandong Jingdao Microelectronics and the BAV21WS by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BAV19W?
5 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
