FDS4685 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; the datasheet gives VDS = -40V and ID = -12A continuous for the device. |
| 2 | S | passive | Source of the P-channel MOSFET, tied in parallel with the other source pins (1, 2, 3). |
| 3 | S | passive | Source of the P-channel MOSFET, tied 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 a threshold of -1.0V to -2.5V. |
| 5 | D | passive | Drain of the P-channel MOSFET, tied in parallel with the other drain pins (5, 6, 7, 8); VDS max is -40V. |
| 6 | D | passive | Drain of the P-channel MOSFET, tied in parallel with the other drain pins (5, 6, 7, 8). |
| 7 | D | passive | Drain of the P-channel MOSFET, tied in parallel with the other drain pins (5, 6, 7, 8). |
| 8 | D | passive | Drain of the P-channel MOSFET, tied in parallel with the other drain pins (5, 6, 7, 8); continuous drain current is -12A. |
