Questions

Is there a KiCad symbol and footprint for the BZX55C12?

Yes. The symbol is Device:D_Zener and the footprint ICs And Semiconductors THD:DO-35, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BZX55C12?

DO-35, with 2 pins. Its footprint is drawn on this page.

Where is the BZX55C12 datasheet?

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

Where can I order the BZX55C12?

JLCPCB lists it as part C87835, with 2,178 in stock; the sellers' links on this page open their listings.

What can replace the BZX55C12?

Parts like it in the library: the BZX55C12 by LGE, the BZT52C12 by GOODWORK, the BZT52C12 by MDD and the ZMM12V by HXY MOSFET. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BZX55C12?

2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
