AO4401-VB from VBsemi Elec, in a SO-8. 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 | S | passive | Source of the P-channel MOSFET; Drain-Source voltage VDS is rated at -30 V maximum. |
| 2 | S | passive | Source of the P-channel MOSFET, tied to the source terminal; continuous source current (diode conduction) is -2.3 A for 10 s and -1.1 A steady state. |
| 3 | S | passive | Source of the P-channel MOSFET, tied to the source terminal; gate-source voltage VGS is limited to ±20 V relative to it. |
| 4 | G | input | Gate of the P-channel MOSFET with gate threshold VGS(th) from -0.7 V to -2.0 V at ID = -250 µA and a maximum VGS of ±20 V. |
| 5 | D | passive | Drain of the P-channel MOSFET, with continuous drain current of -5.8 A (10 s) and -4.1 A steady state at TA = 25 °C. |
| 6 | D | passive | Drain of the P-channel MOSFET, tied to the drain terminal; pulsed drain current IDM is -30 A. |
| 7 | D | passive | Drain of the P-channel MOSFET, tied to the drain terminal; RDS(on) is 0.033 Ω at VGS = -10 V and ID = -5.8 A. |
| 8 | D | passive | Drain of the P-channel MOSFET, tied to the drain terminal; the junction-to-foot (drain) thermal resistance is 24 °C/W typical and 30 °C/W maximum. |
