Overview

The BSS138 is a MOSFET made by MDD in a SOT-23 package with 3 pins. -55℃~+150℃ 1 N-channel 1.1Ω@10V、2Ω@4.5V 1.2V 1.5pF 23.8pF 340mA 500mW 50V 60nC@10V SOT-23 MOSFETs ROHS.

PCBKit's library has its KiCad symbol (Transistor_FET:BSS138, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 168,018 are in stock at JLCPCB (part C427380).

Questions

Is there a KiCad symbol and footprint for the BSS138?

Yes. The symbol is Transistor_FET:BSS138 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 BSS138?

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

Where is the BSS138 datasheet?

MDD publishes it: the Datasheet link on this page opens it.

Where can I order the BSS138?

JLCPCB lists it as part C427380, with 168,018 in stock; the sellers' links on this page open their listings.

What can replace the BSS138?

Parts like it in the library: the 2N7002K by Diodes Incorporated, the BSS138P by Nexperia, the SI2308A by UMW and the SI2310 by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
