Questions

Is there a KiCad symbol and footprint for the Z2E12B?

Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SMB, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the Z2E12B?

SMB, with 2 pins. Its footprint is drawn on this page.

Where is the Z2E12B datasheet?

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

Where can I order the Z2E12B?

JLCPCB lists it as part C7466348, with 2,405 in stock; the sellers' links on this page open their listings.

What can replace the Z2E12B?

Parts like it in the library: the SMBJ5349B by hongjiacheng, the 1SMB5927B by onsemi, the SMBJ5349B-TP by Micro Commercial Components and the SMBJ5349B by BORN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
