Shenzhen Fuman · MOSFETs · SOP-8

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.
