DMG3404L-7 from Diodes Incorporated, 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 terminal of the N-channel MOSFET; gate-source voltage is rated ±20 V (VGSS). |
| 2 | S | passive | Source terminal of the N-channel MOSFET, the reference for gate-source voltage (VGS) and the drain-source rating (VDSS = 30 V). |
| 3 | D | passive | Drain terminal of the N-channel MOSFET; drain-source voltage is rated 30 V (VDSS) with continuous drain current of 5.8 A at TA = +25°C (VGS = 10 V). |
