DMP2240UW-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; the top view shows it at the bottom-left, and the gate-source voltage limit is ±12 V with a threshold VGS(th) of -0.45 V to -1.0 V. |
| 2 | S | passive | Source; the top view shows it at the bottom-right, and the drain-source voltage is rated -20 V. |
| 3 | D | passive | Drain; the top view shows it alone on the top side, and the continuous drain current is -1.5 A at TA = 25°C (pulsed -5 A). |
