Overview
The MMBT3640 is a bipolar Transistors BJT made by onsemi in a SOT-23-3 package with 3 pins. 12V 200mA 225mW PNP SOT-23-3 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_PNP_1B_2E_3C, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-23-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C274693).

Is there a KiCad symbol and footprint for the MMBT3640?
Yes. The symbol is Pinmap_Generic:Q_PNP_1B_2E_3C and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MMBT3640?
SOT-23-3, with 3 pins. Its footprint is drawn on this page.
Where is the MMBT3640 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MMBT3640?
JLCPCB lists it as part C274693, with 0 in stock; the sellers' links on this page open their listings.
What can replace the MMBT3640?
Parts like it in the library: the MMBT2369LT1G by onsemi, the S8050 by powersilicon, the MMS8550-L-TP by Micro Commercial Components and the BFR35APE6327 by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
