Overview
The BU406D is a bipolar made by SPTECH in a TO-252 package with 3 pins. 1 NPN 150V 1V 30MHz 5mA 65W 6V 7A 80 NPN TO-252 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 (EasyEDA_Cloud:TO-252-2_L6.6-W6.1-P4.57-LS9.9-BR-CW, from EasyEDA), ready for a KiCad board. 2,188 are in stock at JLCPCB (part C480154).

Is there a KiCad symbol and footprint for the BU406D?
Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2C_3E and the footprint EasyEDA_Cloud:TO-252-2_L6.6-W6.1-P4.57-LS9.9-BR-CW, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BU406D?
TO-252, with 3 pins. Its footprint is drawn on this page.
Where is the BU406D datasheet?
SPTECH publishes it: the Datasheet link on this page opens it.
Where can I order the BU406D?
JLCPCB lists it as part C480154, with 2,188 in stock; the sellers' links on this page open their listings.
What can replace the BU406D?
Parts like it in the library: the 2SC6076 by ISC, the 2SD1899 by ISC, the MJD47 by ISC and the KSH50TF-ON by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
