HD3401 from High Diode, 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 enhancement-mode MOSFET; gate-source voltage limit is ±12 V, with threshold VGS(th) of -0.7 V min to -1.3 V max at ID = -250 µA. |
| 2 | S | passive | Source of the P-channel MOSFET; body diode forward current IS is -2 A continuous (ISM -25 A pulsed). |
| 3 | D | passive | Drain of the P-channel MOSFET; VDS is rated -30 V and continuous drain current ID is -4.2 A. |
