Overview
The BUT11A is a bipolar made by SPTECH in a TO-220C package with 3 pins. 1 NPN 1.5V 100W 2mA 35 450V 5A 7V NPN Standalone TO-220C 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. 27 are in stock at JLCPCB (part C2907603). 1 open-source board in 1 repository on GitHub use it.

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-220C, with 3 pins. Its footprint is drawn on this page.
Where is the BUT11A datasheet?
SPTECH publishes it: the Datasheet link on this page opens it.
Where can I order the BUT11A?
JLCPCB lists it as part C2907603, with 27 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 BUT11AI by SPTECH and the BUT11A by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BUT11A?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
