LX3400S from ChipLink Tech, 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; drives the N-channel MOSFET with VGS rated ±12V maximum and operation with gate voltage as low as 2.5V (Vth 0.7V min to 1.2V max at 250uA). |
| 2 | S | passive | Source; connects to the body diode anode, with continuous current up to 5.1A (ID) and diode forward current IS of 5.1A. |
| 3 | D | passive | Drain; rated VDS 30V maximum, ID 5.1A continuous and 20A pulsed (IDM), with RDS(ON) of 33mΩ max at VGS=10V. |
