Overview

The BAS31 is a diodes General Purpose made by onsemi in a SOT-23 package with 3 pins. 1 Pair Series Connection 1.25V@400mA 100nA@90V 120V 1A 200mA SOT-23 Diodes - General Purpose ROHS.

PCBKit's library has its KiCad symbol (Diodes:Diode x2 A1C3_A3C2, from CERN's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 535 are in stock at JLCPCB (part C415998).

Questions

Is there a KiCad symbol and footprint for the BAS31?

Yes. The symbol is Diodes:Diode x2 A1C3_A3C2 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BAS31?

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

Where is the BAS31 datasheet?

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

Where can I order the BAS31?

JLCPCB lists it as part C415998, with 535 in stock; the sellers' links on this page open their listings.

What can replace the BAS31?

Parts like it in the library: the SBAS21L by onsemi, the MMBD1503A by onsemi, the BAS19 by Nexperia and the BAV23S by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
