DMN4035LQ-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 ±20V with threshold VGS(TH) of 1V min to 3V max at ID = 250μA. |
| 2 | S | passive | Source; body diode forward current up to 4.6A, with continuous drain current of 4.6A at VGS = 10V and TA = +25°C. |
| 3 | D | passive | Drain; drain-source voltage rated at 40V, continuous current 4.6A and pulsed current 25A (10µs pulse, 1% duty cycle). |
