DMN2004WKQ-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, ESD-protected by an internal gate protection diode, with a maximum gate-source voltage of ±8 V and a threshold of 0.5 to 1.0 V at ID = 250 µA. |
| 2 | S | passive | Source terminal of the N-channel MOSFET, with a body diode to the drain (VSD 0.5 to 1.4 V at IS = 115 mA). |
| 3 | D | passive | Drain terminal of the N-channel MOSFET, rated for VDSS of 20 V and 540 mA continuous drain current (1.5 A pulsed). |
