Overview
The BD140 is a bipolar Transistors BJT made by onsemi in a TO-225-3 package with 3 pins. -55℃~+150℃ 1.25W 1.5A 100nA 500mV 80V PNP TO-225-3 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BD140, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-126-3_Vertical, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C605317).

Is there a KiCad symbol and footprint for the BD140?
Yes. The symbol is Transistor_BJT:BD140 and the footprint Package_TO_SOT_THT:TO-126-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BD140?
TO-225-3, with 3 pins. Its footprint is drawn on this page.
Where is the BD140 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the BD140?
JLCPCB lists it as part C605317, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BD140?
Parts like it in the library: the BD135 by STMicroelectronics, the BD435STU by onsemi and the BD438STU by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
