AO3401 from Guangdong Hottech, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate. High-impedance MOSFET control terminal. VGS(th) between -0.7 V and -1.3 V; absolute maximum VGS = ±12 V. Drives channel conduction between Drain and Source. |
| 2 | S | passive | Source. P-channel MOSFET source terminal, typically tied to the positive supply in high-side switching. Body diode anode is internally connected here (VSD ≈ -1 V at IS = -1 A). |
| 3 | D | passive | Drain. P-channel MOSFET drain terminal, typically tied to the load. VDS rated to -30 V; continuous ID = -4.2 A. Body diode cathode is internally connected here. |
