AO3406A from ElecSuper, 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 | Gate | input | Gate terminal of the N-channel MOSFET; the datasheet rates gate-source voltage VGS at ±20 V. |
| 2 | Source | passive | Source terminal of the N-channel MOSFET; the body diode forward voltage VSD is 1.5 V max at IS = 3.6 A with VGS = 0 V. |
| 3 | Drain | passive | Drain terminal of the N-channel MOSFET; the datasheet rates drain-source voltage BVDSS at 30 V and continuous drain current ID at 4.3 A at TA = 25°C. |
