Overview

The BSS139 is a MOSFET made by TECH PUBLIC in a SOT-23 package with 3 pins.

PCBKit's library has its KiCad symbol (Transistors:N-SIPMOS-D DM 1G 2S 3D, from CERN's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 7,301 are in stock at JLCPCB (part C28646321).

Questions

Is there a KiCad symbol and footprint for the BSS139?

Yes. The symbol is Transistors:N-SIPMOS-D DM 1G 2S 3D 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 BSS139?

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

Where is the BSS139 datasheet?

TECH PUBLIC publishes it: the Datasheet link on this page opens it.

Where can I order the BSS139?

JLCPCB lists it as part C28646321, with 7,301 in stock; the sellers' links on this page open their listings.

What can replace the BSS139?

Parts like it in the library: the 2N7002K by Diodes Incorporated, the BSS138P by Nexperia, the BSS138K by ElecSuper and the BSS138 by ElecSuper. Check their datasheets: a part that fits the footprint may still differ in its ratings.
