Is there a KiCad symbol and footprint for the DB3?
Yes. The symbol is Diode:DB3 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 DB3?
DO-35, with 2 pins. Its footprint is drawn on this page.
Where is the DB3 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the DB3?
JLCPCB lists it as part C60568, with 41,015 in stock; the sellers' links on this page open their listings.
What can replace the DB3?
Parts like it in the library: the DB3 by LGE, the DB4 by LGE, the DB3 by Changzhou Starsea Elec and the DB3 by luJing. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the DB3?
10 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
