AGM308SR from AGM-Semi, 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, tied internally with pins 2 and 3; pin 1 is the marked corner on the top view. |
| 2 | S | passive | Source of the N-channel MOSFET, tied internally with pins 1 and 3. |
| 3 | S | passive | Source of the N-channel MOSFET, tied internally with pins 1 and 2. |
| 4 | G | input | Gate of the N-channel MOSFET, with a maximum gate-source voltage of ±20 V and a threshold of 1.2 to 2.2 V. |
| 5 | D | passive | Drain of the MOSFET, tied internally with pins 6, 7 and 8, with a drain-source voltage of 30 V and a continuous current of 17 A. |
| 6 | D | passive | Drain of the MOSFET, tied internally with pins 5, 7 and 8. |
| 7 | D | passive | Drain of the MOSFET, tied internally with pins 5, 6 and 8. |
| 8 | D | passive | Drain of the MOSFET, tied internally with pins 5, 6 and 7. |
