Overview
The BUT11A is a bipolar made by onsemi in a TO-220-3 package with 3 pins. 1.5V@2.5A,500mA 100W 1mA 450V 5A NPN TO-220-3 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BUT11A, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-220-3_Vertical, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3200980).

Is there a KiCad symbol and footprint for the BUT11A?
Yes. The symbol is Transistor_BJT:BUT11A and the footprint Package_TO_SOT_THT:TO-220-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BUT11A?
TO-220-3, with 3 pins. Its footprint is drawn on this page.
Where is the BUT11A datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the BUT11A?
JLCPCB lists it as part C3200980, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BUT11A?
Parts like it in the library: the JMSH1509AC-U by Jiangsu JieJie Microelectronics, the BUT11 by SPTECH, the BUT11A by SPTECH and the BUT11AI by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
