Overview
The DB4 is a trigger Diode made by STMicroelectronics in a DO-35 package with 2 pins. -40℃~+125℃@(Tj) 10uA 2A 2us 35V~45V 3V 40V 50uA 5V 5V DO-35 Trigger Diodes ROHS.
PCBKit's library has its KiCad symbol (Diode:DB4, from KiCad's library) and its footprint (Diode_THT:D_DO-35_SOD27_P7.62mm_Horizontal, from KiCad's library), ready for a KiCad board. 5,471 are in stock at JLCPCB (part C2499).

Questions
Is there a KiCad symbol and footprint for the DB4?
Yes. The symbol is Diode:DB4 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 DB4?
DO-35, with 2 pins. Its footprint is drawn on this page.
Where is the DB4 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the DB4?
JLCPCB lists it as part C2499, with 5,471 in stock; the sellers' links on this page open their listings.
What can replace the DB4?
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.
