Overview
The MMBT3904 is a bipolar Transistors BJT made by HT in a SOT-23 package with 3 pins. 1 NPN 100 100nA 200mA 200mW 300MHz 300mV 40V 6V NPN SOT-23 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:MMBT3904, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 2,930 are in stock at JLCPCB (part C179725).

Is there a KiCad symbol and footprint for the MMBT3904?
Yes. The symbol is Transistor_BJT:MMBT3904 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MMBT3904?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MMBT3904 datasheet?
HT publishes it: the Datasheet link on this page opens it.
Where can I order the MMBT3904?
JLCPCB lists it as part C179725, with 2,930 in stock; the sellers' links on this page open their listings.
What can replace the MMBT3904?
Parts like it in the library: the PBSS4140T by Nexperia, the S9012 by Guangdong Hottech, the S8550-2TY by ShunYe and the 13001 by HT. Check their datasheets: a part that fits the footprint may still differ in its ratings.
