Questions

Is there a KiCad symbol and footprint for the 1N4122UR?

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

What package is the 1N4122UR?

DO-213AA, with 2 pins. Its footprint is drawn on this page.

Where is the 1N4122UR datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the 1N4122UR?

JLCPCB lists it as part C6395956, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 1N4122UR?

Parts like it in the library: the ZMM36 by JSMSEMI, the ZMM36V by RUILON, the ZMM36PF-M by STMicroelectronics and the ZMM36 by Zhengxin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
