Questions

Is there a KiCad symbol and footprint for the SM18?

Yes. the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SM18?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the SM18 datasheet?

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

Where can I order the SM18?

JLCPCB lists it as part C5253560, with 2,433 in stock; the sellers' links on this page open their listings.

What can replace the SM18?

Parts like it in the library: the SZMMBZ18VALT1G-HXY by HXY MOSFET, the BZX84B18 by LGE, the MMBZ20VAL-TP by TECH PUBLIC and the TPESD18WUS3G by TECH PUBLIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
