Overview

The FMMT734 is a darlington Transistor made by Diodes Incorporated in a SOT-23 package with 3 pins. -100V, -800mA, PNP Darlington Transistor.

PCBKit's library has its KiCad symbol (Transistors:PNP DARLINGTON B1 E2 C3, from CERN's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C5249005). 4 open-source boards in 3 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the FMMT734?

Yes. The symbol is Transistors:PNP DARLINGTON B1 E2 C3 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 FMMT734?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the FMMT734 datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the FMMT734?

JLCPCB lists it as part C5249005, with 0 in stock; the sellers' links on this page open their listings.

What can replace the FMMT734?

Parts like it in the library: the FMMT634TA by Diodes Incorporated, the FMMT734TA by Diodes Incorporated, the FMMT634QTA by Diodes Incorporated and the BCV 47 E6327 by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the FMMT734?

4 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
