**MSKSEMI** · MOSFETs · SOP-8

AO4612-MS from MSKSEMI, 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 | S1 | passive | Source of MOSFET 1, assumed to be the N-channel device (VDS 60V, ID 5.0A at TA=25C). |
| 2 | G1 | input | Gate of MOSFET 1, assumed to be the N-channel device, with a gate-source voltage rating of ±20V. |
| 3 | S2 | passive | Source of MOSFET 2, assumed to be the P-channel device (VDS -60V, ID -4.0A at TA=25C). |
| 4 | G2 | input | Gate of MOSFET 2, assumed to be the P-channel device, with a gate-source voltage rating of ±20V. |
| 5 | D2 | passive | Drain of MOSFET 2, assumed to be the P-channel device, with a drain-source voltage rating of -60V; connected to pin 6. |
| 6 | D2 | passive | Drain of MOSFET 2, assumed to be the P-channel device, with a drain-source voltage rating of -60V; connected to pin 5. |
| 7 | D1 | passive | Drain of MOSFET 1, assumed to be the N-channel device, with a drain-source voltage rating of 60V; connected to pin 8. |
| 8 | D1 | passive | Drain of MOSFET 1, assumed to be the N-channel device, with a drain-source voltage rating of 60V; connected to pin 7. |
