Is there a KiCad symbol and footprint for the SM15T18AY?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SMC, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SM15T18AY?
SMC, with 2 pins. Its footprint is drawn on this page.
Where is the SM15T18AY datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the SM15T18AY?
JLCPCB lists it as part C1973509, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SM15T18AY?
Parts like it in the library: the 1.5SMC20A/TR13 by Brightking, the TPSMC20CA by Littelfuse, the TPSMC20A by Littelfuse and the 1.5SMC20A by Littelfuse. Check their datasheets: a part that fits the footprint may still differ in its ratings.
