Overview
The BU102 is a bipolar made by SPTECH in a TO-3 package with 3 pins. 1 NPN 100W 100uA 120 150V 2V 6V 7A NPN Standalone TO-3 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NPN_1B_2C_3E, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_THT:TO-3, from KiCad's library), ready for a KiCad board. 9 are in stock at JLCPCB (part C2907832).

Is there a KiCad symbol and footprint for the BU102?
Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2C_3E and the footprint Package_TO_SOT_THT:TO-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BU102?
TO-3, with 3 pins. Its footprint is drawn on this page.
Where is the BU102 datasheet?
SPTECH publishes it: the Datasheet link on this page opens it.
Where can I order the BU102?
JLCPCB lists it as part C2907832, with 9 in stock; the sellers' links on this page open their listings.
What can replace the BU102?
Parts like it in the library: the 2N3055 by JSMSEMI, the 2N3055A by SPTECH, the MJ2955 by SPTECH and the MJ15022 by SPTECH. Check their datasheets: a part that fits the footprint may still differ in its ratings.
