Questions

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-34, with 2 pins. Its footprint is drawn on this page.

Where is the DB3 datasheet?

XCH publishes it: the Datasheet link on this page opens it.

Where can I order the DB3?

JLCPCB lists it as part C7440225, with 2,279 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 STMicroelectronics, the DB3 by LGE, the DB4 by LGE and the DB3 by Changzhou Starsea Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
