SI9433BDY

TECH PUBLIC · MOSFETs · SOP-8

SI9433BDY from TECH PUBLIC, in a SOP-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; source-drain body diode continuous current max -1.5A at TA=25°C.
2 S passive Source of the P-channel MOSFET; source-drain body diode continuous current max -1.5A at TA=25°C.
3 S passive Source of the P-channel MOSFET; source-drain body diode continuous current max -1.5A at TA=25°C.
4 G input Gate of the P-channel MOSFET; gate-source voltage max ±12V, threshold -0.4V min to -1.0V max.
5 D passive Drain of the P-channel MOSFET; drain-source voltage max -20V, continuous drain current -7.5A at TA=25°C.
6 D passive Drain of the P-channel MOSFET; drain-source voltage max -20V, continuous drain current -7.5A at TA=25°C.
7 D passive Drain of the P-channel MOSFET; drain-source voltage max -20V, continuous drain current -7.5A at TA=25°C.
8 D passive Drain of the P-channel MOSFET; drain-source voltage max -20V, continuous drain current -7.5A at TA=25°C.
