Overview
The 2SB817 is a bipolar made by SPTECH in a TO-3PN package with 3 pins. 1 PNP 100W 100uA 12A 140V 15MHz 2.5V 200 6V PNP TO-3PN Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:2SB817, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-3PB-3_Vertical, from KiCad's library), ready for a KiCad board. 51 are in stock at JLCPCB (part C480230). 1 open-source board in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the 2SB817?
Yes. The symbol is Transistor_BJT:2SB817 and the footprint Package_TO_SOT_THT:TO-3PB-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 2SB817?
TO-3PN, with 3 pins. Its footprint is drawn on this page.
Where is the 2SB817 datasheet?
SPTECH publishes it: the Datasheet link on this page opens it.
Where can I order the 2SB817?
JLCPCB lists it as part C480230, with 51 in stock; the sellers' links on this page open their listings.
What can replace the 2SB817?
Parts like it in the library: the HT2SA1943-ODZ by HTCSEMI, the MJW18020 by onsemi, the TIP36CW by STMicroelectronics and the 2SD1047 by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the 2SB817?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
