Overview
The BDX34B is a darlington Transistor made by Texas Instruments in a TO-220 package with 3 pins. 10A 2.5V 70W 750 80V PNP TO-220 Darlington Transistors.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:BDX34B, from EasyEDA) and its footprint (EasyEDA_Cloud:TO-220-3_L10.0-W4.6-P2.54-L, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C4365985).

Is there a KiCad symbol and footprint for the BDX34B?
Yes. The symbol is EasyEDA_Cloud:BDX34B and the footprint EasyEDA_Cloud:TO-220-3_L10.0-W4.6-P2.54-L, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BDX34B?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the BDX34B datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the BDX34B?
JLCPCB lists it as part C4365985, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BDX34B?
Parts like it in the library: the D44E2 by Texas Instruments and the BDX33C by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
