BLM3400S3 from TECH PUBLIC, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate of the N-channel MOSFET, rated for ±12 V gate-source voltage with a gate threshold of 0.7 V min to 1.4 V max at VDS=VGS, ID=250 µA. |
| 2 | S | passive | Source of the N-channel MOSFET, the reference terminal for the gate drive and the body-diode anode, with diode forward current up to 5.8 A. |
| 3 | D | passive | Drain of the N-channel MOSFET, rated for 30 V drain-source voltage and 5.8 A continuous (30 A pulsed) drain current. |
