Overview
The MMBF170Q is a MOSFET made by Diodes Incorporated in a SOT-23-3 package with 3 pins.
PCBKit's library has its KiCad symbol (Transistor_FET:MMBF170, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C6673446).

Questions
Is there a KiCad symbol and footprint for the MMBF170Q?
Yes. The symbol is Transistor_FET:MMBF170 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 MMBF170Q?
SOT-23-3, with 3 pins. Its footprint is drawn on this page.
Where is the MMBF170Q datasheet?
Diodes Incorporated publishes it: the Datasheet link on this page opens it.
Where can I order the MMBF170Q?
JLCPCB lists it as part C6673446, with 0 in stock; the sellers' links on this page open their listings.
What can replace the MMBF170Q?
Parts like it in the library: the ST3422A by STANSON Tech., the AP5N10S by ALLPOWER, the FDN5618P by onsemi and the SI2309CDS-T1-GE3 by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
