Is there a KiCad symbol and footprint for the SMAZ18?
Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMAZ18?
SMA, with 2 pins. Its footprint is drawn on this page.
Where is the SMAZ18 datasheet?
Diodes Incorporated publishes it: the Datasheet link on this page opens it.
Where can I order the SMAZ18?
JLCPCB lists it as part C110525, with 5,887 in stock; the sellers' links on this page open their listings.
What can replace the SMAZ18?
Parts like it in the library: the SZA18A by Leshan Radio (LRC), the 1SMA5931B by onsemi, the SML4746A-E3 by Vishay Intertechnology and the SMA4746A by DOWO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
