Questions

Is there a KiCad symbol and footprint for the TSB40U?

Yes. 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 TSB40U?

DO-214AC, with 5 pins. Its footprint is drawn on this page.

Where is the TSB40U datasheet?

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

Where can I order the TSB40U?

JLCPCB lists it as part C53514098, with 5,000 in stock; the sellers' links on this page open their listings.

What can replace the TSB40U?

Parts like it in the library: the SMAJ40A by Shenzhen JDT Fuse, the SMAJ40CA by Shenzhen JDT Fuse, the SMAJ40CA by ShunYe and the SMAJ40A by TDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
