DO3407B from DOINGTER, 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 of the P-channel MOSFET; gate-source voltage limited to ±20 V, threshold VGS(th) -1 to -2.5 V. |
| 2 | D | passive | Drain of the P-channel MOSFET; drain-source voltage -30 V max, continuous drain current -4.1 A at TA=25℃. |
| 3 | S | passive | Source of the P-channel MOSFET; body diode runs from drain to source with continuous current up to -4.1 A. |
