AO3402 from GOODWORK, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GATE | input | Gate of the N-channel enhancement MOSFET; the datasheet limits gate-source voltage to VGS ±12 V. |
| 2 | SOURCE | passive | Source of the N-channel MOSFET; the datasheet gives a body diode forward voltage VSD of 1 V max at IS = 1 A, VGS = 0 V. |
| 3 | DRAIN | passive | Drain of the N-channel MOSFET; the datasheet limits drain-source voltage to 30 V and continuous drain current to 4 A at Ta = 25 ℃. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
AO3402 - Footprint:
Package_TO_SOT_SMD:SOT-23 - 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.0 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
