4009S from HL, 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 N-channel MOSFET (one of three tied source pins, SOP8 pin configuration drawing). |
| 2 | S | passive | Source of the N-channel MOSFET (one of three tied source pins, SOP8 pin configuration drawing). |
| 3 | S | passive | Source of the N-channel MOSFET (one of three tied source pins, SOP8 pin configuration drawing). |
| 4 | G | input | Gate of the N-channel MOSFET, rated ±20 V gate-source with a 1 to 2 V threshold at 250 µA. |
| 5 | D | passive | Drain of the N-channel MOSFET, rated 40 V drain-source and 9 A continuous (one of four tied drain pins). |
| 6 | D | passive | Drain of the N-channel MOSFET, rated 40 V drain-source and 9 A continuous (one of four tied drain pins). |
| 7 | D | passive | Drain of the N-channel MOSFET, rated 40 V drain-source and 9 A continuous (one of four tied drain pins). |
| 8 | D | passive | Drain of the N-channel MOSFET, rated 40 V drain-source and 9 A continuous (one of four tied drain pins). |
