Overview

The BLM3400 is a MOSFET made by BL in a SOT-23 package with 3 pins. -55℃~+150℃ 1 N-channel 1.4V 1.4W 30V 5.8A 59mΩ@2.5V 623pF 77pF 9.5nC@4.5V 99pF N-Channel SOT-23 MOSFETs ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2S_3D, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 30,763 are in stock at JLCPCB (part C169245). 1 open-source board in 1 repository on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the BLM3400?

Yes. The symbol is Pinmap_Generic:Q_NMOS_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 BLM3400?

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

Where is the BLM3400 datasheet?

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

Where can I order the BLM3400?

JLCPCB lists it as part C169245, with 30,763 in stock; the sellers' links on this page open their listings.

What can replace the BLM3400?

Parts like it in the library: the AO3400A by UMW, the AO3400 by Guangdong Hottech, the IRLML6344TRPBF-HXY by HXY MOSFET and the MDD3400 by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BLM3400?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
