SI9433DY-T1-E3-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, tied to pins 2 and 3; drain-source voltage rated -20 V. |
| 2 | S | passive | Source of the P-channel MOSFET, tied to pins 1 and 3; continuous source-drain diode current is -6 A at TC = 25 °C. |
| 3 | S | passive | Source of the P-channel MOSFET, tied to pins 1 and 2; pulsed drain current is limited to -50 A. |
| 4 | G | input | Gate of the P-channel MOSFET; gate-source voltage is limited to ±12 V and the threshold is -0.5 V to -1.2 V at ID = -250 µA. |
| 5 | D | passive | Drain of the P-channel MOSFET, tied to pins 6, 7 and 8; RDS(on) is 0.015 Ω at VGS = -4.5 V. |
| 6 | D | passive | Drain of the P-channel MOSFET, tied to pins 5, 7 and 8; drain-source voltage rated -20 V. |
| 7 | D | passive | Drain of the P-channel MOSFET, tied to pins 5, 6 and 8; continuous drain current is -13 A at TC = 25 °C. |
| 8 | D | passive | Drain of the P-channel MOSFET, tied to pins 5, 6 and 7; RDS(on) is 0.021 Ω at VGS = -2.5 V. |
