Overview
The ZTX951 is a bipolar made by Diodes Incorporated in a E-Line-3 package with 3 pins. -55℃~+200℃@(Tj) 1.2W 100@1A,1V 120MHz 300mV@4A,400mA 4A 50nA 60V PNP E-Line(TO-92) Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_PNP_1E_2B_3C, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-92-3_L4.8-W3.7-P1.27-L-1, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C2987003). 1 open-source board in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the ZTX951?
Yes. The symbol is Pinmap_Generic:Q_PNP_1E_2B_3C and the footprint EasyEDA_Cloud:TO-92-3_L4.8-W3.7-P1.27-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ZTX951?
E-Line-3, with 3 pins. Its footprint is drawn on this page.
Where is the ZTX951 datasheet?
Diodes Incorporated publishes it: the Datasheet link on this page opens it.
Where can I order the ZTX951?
JLCPCB lists it as part C2987003, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ZTX951?
Parts like it in the library: the DTC114Y by onsemi, the DTC123E by onsemi, the SS9012GTA-ON by onsemi and the 2SA1317S-AC by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the ZTX951?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
