Overview
The MMBTA56 is a bipolar made by DIOTEC in a SOD-323 package with 3 pins. -55℃~+150℃ 100 100nA 250mV 500mA 50MHz 80V PNP SOD-323 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:MMBTA56, from KiCad's library) and its footprint (EasyEDA_Cloud:SOT-23-3_L2.9-W1.3-P0.95-LS2.4-BR, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C3199468).

Is there a KiCad symbol and footprint for the MMBTA56?
Yes. The symbol is Transistor_BJT:MMBTA56 and the footprint EasyEDA_Cloud:SOT-23-3_L2.9-W1.3-P0.95-LS2.4-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MMBTA56?
SOD-323, with 3 pins. Its footprint is drawn on this page.
Where is the MMBTA56 datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the MMBTA56?
JLCPCB lists it as part C3199468, with 0 in stock; the sellers' links on this page open their listings.
What can replace the MMBTA56?
