AO4401-VB

VBsemi Elec · MOSFETs · SO-8

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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: VBsemi Elec datasheet (8 pp, sha256 305022af60f16f4d, retrieved 2026-11-02, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
