Questions

Is there a KiCad symbol and footprint for the HZ12B1?

Yes. The symbol is Device:D_Zener and the footprint EasyEDA_Cloud:DO-35_BD2.0-L4.0-P8.00-D0.5-FD, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HZ12B1?

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

Where is the HZ12B1 datasheet?

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

Where can I order the HZ12B1?

JLCPCB lists it as part C68349, with 0 in stock; the sellers' links on this page open their listings.

What can replace the HZ12B1?

Parts like it in the library: the 5V1HCB by EIC Semicon, the BZX55C24 by LGE, the BZX55C27 by LGE and the BZX55C4V3 by LGE. Check their datasheets: a part that fits the footprint may still differ in its ratings.
