Questions

Is there a KiCad symbol and footprint for the SACB45?

Yes. The symbol is Device:D_TVS and 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 SACB45?

SMB, with 2 pins. Its footprint is drawn on this page.

Where is the SACB45 datasheet?

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

Where can I order the SACB45?

JLCPCB lists it as part C1975395, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SACB45?

Parts like it in the library: the SMBJ45A by hongjiacheng, the SMBJ45A by BORN, the SMBJ45CA by BORN and the SMBJ45A by FOSAN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
