DMN31D5L-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, ESD-protected via an internal gate protection diode; VGSS rating ±20 V and threshold VGS(TH) 0.8 V to 1.6 V at ID = 250 µA. |
| 2 | S | passive | Source terminal of the N-channel MOSFET, with the body diode (IS max 0.3 A) running from source to drain. |
| 3 | D | passive | Drain terminal, with VDSS of 30 V and continuous drain current of 0.5 A at TA = +25°C (VGS = 4 V). |
