What package is the TL431BSA?

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

Where is the TL431BSA datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the TL431BSA?

JLCPCB lists it as part C97730, with 4,405 in stock; the sellers' links on this page open their listings.

What can replace the TL431BSA?

Parts like it in the library: the TL431 by FOSAN, the AZ431AN-ATRE1 by Diodes Incorporated, the AZ431AN-ATRG1 by Diodes Incorporated and the TL431 by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
