Overview
The BAS31 is an avalanche Diode made by Nexperia in a SOT-23 package with 3 pins. 1 Pair Series Connection 1.25V@400mA 100nA@90V 10A 50ns 600mA 90V SOT-23 Avalanche Diodes 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. 439 are in stock at JLCPCB (part C549220).

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?
Nexperia publishes it: the Datasheet link on this page opens it.
Where can I order the BAS31?
JLCPCB lists it as part C549220, with 439 in stock; the sellers' links on this page open their listings.
What can replace the BAS31?
Parts like it in the library: the PLVA2668A by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
