AO3404A-JSM from JSMSEMI, in a SOT-23-3L. 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; the top view shows it at the upper left, and VGSS is rated ±20 V with a typical threshold of 1 V min to 2 V max at ID=250uA. |
| 2 | S | passive | Source; the top view shows it at the lower left, and the continuous source (diode) current is rated at 1.5 A. |
| 3 | D | passive | Drain; the top view shows it on the right side, with VDSS rated at 30 V and continuous drain current of 6.0 A at TC=25℃ (pulsed 20 A). |
