45N18 from Shenzhen Fuman, 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 terminal of the N-channel MOSFET, connected internally to the other source pins (2, 3). |
| 2 | S | passive | Source terminal of the N-channel MOSFET, connected internally to the other source pins (1, 3). |
| 3 | S | passive | Source terminal of the N-channel MOSFET, connected internally to the other source pins (1, 2). |
| 4 | G | input | Gate terminal of the N-channel MOSFET with a maximum gate-source voltage of ±20 V. |
| 5 | D | passive | Drain terminal of the MOSFET, connected to the other drain pins (6, 7, 8), rated for 45 V drain-source voltage. |
| 6 | D | passive | Drain terminal of the MOSFET, connected to the other drain pins (5, 7, 8), rated for 45 V drain-source voltage. |
| 7 | D | passive | Drain terminal of the MOSFET, connected to the other drain pins (5, 6, 8), rated for 45 V drain-source voltage. |
| 8 | D | passive | Drain terminal of the MOSFET, connected to the other drain pins (5, 6, 7), rated for 45 V drain-source voltage. |
