VBsemi Elec · MOSFETs · SO-8
AO4433-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; VDS rated -30 V and continuous source-drain diode current -3.5 A at TC = 25 °C. |
| 2 | S | passive | Source of the P-channel MOSFET, tied to the same source as pins 1 and 3. |
| 3 | S | passive | Source of the P-channel MOSFET, tied to the same source as pins 1 and 2. |
| 4 | G | input | Gate of the P-channel MOSFET; gate-source voltage limit is ±20 V with threshold of -1.0 V min to -2.5 V max at ID = -250 µA. |
| 5 | D | passive | Drain of the P-channel MOSFET; continuous drain current -9.0 A at TC = 25 °C and pulsed drain current -30 A. |
| 6 | D | passive | Drain of the P-channel MOSFET, tied to the same drain as pins 5, 7 and 8. |
| 7 | D | passive | Drain of the P-channel MOSFET, tied to the same drain as pins 5, 6 and 8. |
| 8 | D | passive | Drain of the P-channel MOSFET, tied to the same drain as pins 5, 6 and 7. |
