Is there a KiCad symbol and footprint for the CDBA340-HF?
Yes. The symbol is Diode:CDBA340-HF and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CDBA340-HF?
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
Where is the CDBA340-HF datasheet?
Comchip publishes it: the Datasheet link on this page opens it.
Where can I order the CDBA340-HF?
JLCPCB lists it as part C2885988, with 9,879 in stock; the sellers' links on this page open their listings.
What can replace the CDBA340-HF?
Parts like it in the library: the SS34 by MDD, the SS54 by MDD, the SS54 by hongjiacheng and the SS56 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the CDBA340-HF?
11 boards in 9 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
