STANSON Tech · MOSFETs · SOP-8

ST9435A from STANSON Tech, 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; continuous source (diode conduction) current is rated at -2.3A.
2 S passive Source of the P-channel MOSFET, connected in parallel with the other source pins (1, 2, 3).
3 S passive Source of the P-channel MOSFET, connected in parallel with the other source pins (1, 2, 3).
4 G input Gate of the P-channel MOSFET; absolute maximum gate-source voltage is ±20V with threshold of -1.0V to -3.0V.
5 D passive Drain of the P-channel MOSFET; drain-source voltage rating is -30V.
6 D passive Drain of the P-channel MOSFET, connected in parallel with the other drain pins (5, 6, 7, 8).
7 D passive Drain of the P-channel MOSFET, connected in parallel with the other drain pins (5, 6, 7, 8).
8 D passive Drain of the P-channel MOSFET, connected in parallel with the other drain pins (5, 6, 7, 8).
