Overview
The MJD350T4 is a bipolar made by STMicroelectronics in a TO-252 package with 3 pins. -65℃~+150℃ 1 PNP 100uA 15W 30 300V 3V 500mA PNP TO-252 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_PNP_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. 2,201 are in stock at JLCPCB (part C67351). 2 open-source boards in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the MJD350T4?
Yes. The symbol is Pinmap_Generic:Q_PNP_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 MJD350T4?
TO-252, with 3 pins. Its footprint is drawn on this page.
Where is the MJD350T4 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the MJD350T4?
JLCPCB lists it as part C67351, with 2,201 in stock; the sellers' links on this page open their listings.
What can replace the MJD350T4?
Parts like it in the library: the MJD31C by onsemi, the NJD2873 by onsemi, the BU406D by SPTECH and the TIP122D by Foshan Blue Rocket Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the MJD350T4?
2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
