Overview

The BLM3401 is a MOSFET made by BL in a SOT-23 package with 3 pins. 1 P-Channel 1.2W 1.3V 115pF 30V 4.2A 55mΩ@10V 75pF 9.5nC@4.5V 950pF P-Channel SOT-23 MOSFETs ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_PMOS_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. 29 are in stock at JLCPCB (part C90479).

Questions

Is there a KiCad symbol and footprint for the BLM3401?

Yes. The symbol is Pinmap_Generic:Q_PMOS_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 BLM3401?

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

Where is the BLM3401 datasheet?

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

Where can I order the BLM3401?

JLCPCB lists it as part C90479, with 29 in stock; the sellers' links on this page open their listings.

What can replace the BLM3401?

Parts like it in the library: the AO3400A by Alpha & Omega Semiconductor, the AO3400A by UMW, the AO3401A by UMW and the AO3400 by Guangdong Hottech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
