Is there a KiCad symbol and footprint for the BAV103?
Yes. The symbol is Device:D and the footprint Diode_SMD:D_MiniMELF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BAV103?
SOD-80, with 2 pins. Its footprint is drawn on this page.
Where is the BAV103 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the BAV103?
JLCPCB lists it as part C3313132, with 4,624 in stock; the sellers' links on this page open their listings.
What can replace the BAV103?
Parts like it in the library: the BAV103-GS08 by Vishay Intertechnology, the BAV103 by LGE, the CLL2003 TR PBFREE by Central Semicon and the JAN1N5196UR/TR by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BAV103?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
