DMG2305UXQ-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; gate-source voltage limited to ±8V (VGSS), with threshold VGS(TH) of -0.5V to -0.9V at ID = -250µA. |
| 2 | S | passive | Source of the P-channel MOSFET; continuous drain current is -4.2A steady state at TA = +25°C (VGS = -4.5V, 1-inch square copper pad). |
| 3 | D | passive | Drain; drain-source voltage rated -20V (VDSS), pulsed drain current -15A (IDM). |
