Questions

Is there a KiCad symbol and footprint for the CDBU40-HF?

Yes. The symbol is Diode:CDBU40-HF and the footprint Diode_SMD:D_0603_1608Metric, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CDBU40-HF?

SOD-523F, with 2 pins. Its footprint is drawn on this page.

Where is the CDBU40-HF datasheet?

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

Where can I order the CDBU40-HF?

JLCPCB lists it as part C3012735, with 16,860 in stock; the sellers' links on this page open their listings.

What can replace the CDBU40-HF?

Parts like it in the library: the SD0603S040S0R2 by Kyocera AVX, the CD0603-B0340R by Bourns, the NSR20F40NX by onsemi and the CD0603-B0240R by Bourns. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the CDBU40-HF?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
