Questions

Is there a KiCad symbol and footprint for the SMPJ177TR?

Yes. The symbol is EasyEDA_Cloud:SMP4391 and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMPJ177TR?

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

Where is the SMPJ177TR datasheet?

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

Where can I order the SMPJ177TR?

JLCPCB lists it as part C20515942, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SMPJ177TR?

Parts like it in the library: the MMBFJ110 by onsemi, the IF140ST3 by InterFET, the IF140ST3TR by InterFET and the SMP4391 by InterFET. Check their datasheets: a part that fits the footprint may still differ in its ratings.
