DMN2004WK-7 from Diodes Incorporated, in a SOT-323. 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 of the N-channel MOSFET with an internal gate protection diode (ESD protected up to 2kV), gate-source voltage limited to ±8 V with threshold of 0.5 to 1.0 V. |
| 2 | S | passive | Source terminal of the N-channel MOSFET, shown at the bottom right of the top view. |
| 3 | D | passive | Drain terminal of the N-channel MOSFET (VDSS 20 V, continuous drain current 540 mA), the single pin on the top side of the top view. |
