Questions

Is there a KiCad symbol and footprint for the TD9521?

Yes. The symbol is EasyEDA_Cloud:TD9521 and the footprint Package_TO_SOT_SMD:SOT-23-5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TD9521?

SOT-23-5, with 5 pins. Its footprint is drawn on this page.

Where is the TD9521 datasheet?

Techcode Semicon publishes it: the Datasheet link on this page opens it.

Where can I order the TD9521?

JLCPCB lists it as part C193267, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TD9521?

Parts like it in the library: the APL3511BBI-TRG by Anpec Elec, the APL3511DBI-TRG by Anpec Elec and the STI9712 by TMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
