Questions
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-126, with 3 pins. Its footprint is drawn on this page.
Where is the BD140 datasheet?
DDF publishes it: the Datasheet link on this page opens it.
Where can I order the BD140?
JLCPCB lists it as part C50229569, with 9 in stock; the sellers' links on this page open their listings.
What can replace the BD140?
Parts like it in the library: the BD139 by STMicroelectronics, the BD140 by STMicroelectronics, the BD139-16 by STMicroelectronics and the BD139(RANGE:100-250) by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
