Questions

Is there a KiCad symbol and footprint for the SMTPA120?

Yes. 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 SMTPA120?

DO-214AA, with 2 pins. Its footprint is drawn on this page.

Where is the SMTPA120 datasheet?

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

Where can I order the SMTPA120?

JLCPCB lists it as part C2650087, with 250 in stock; the sellers' links on this page open their listings.

What can replace the SMTPA120?

Parts like it in the library: the TISP4240M3BJR-S by Bourns, the P0080SC by WPMtek, the P3100SC by TECH PUBLIC and the TISP4070H3BJR-S by Bourns. Check their datasheets: a part that fits the footprint may still differ in its ratings.
