IRF7403TR from UMW, 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 (pins 1, 2 and 3 are all listed as SOURCE in the pinning table). |
| 2 | S | passive | SOURCE terminal of the N-channel MOSFET (pins 1, 2 and 3 are all listed as SOURCE in the pinning table). |
| 3 | S | passive | SOURCE terminal of the N-channel MOSFET (pins 1, 2 and 3 are all listed as SOURCE in the pinning table). |
| 4 | G | input | GATE terminal; the datasheet rates gate-to-source voltage VGS at ±20 V. |
| 5 | D | passive | DRAIN terminal (pins 5, 6, 7 and 8 are all listed as DRAIN in the pinning table); drain-source breakdown voltage V(BR)DSS is 30 V. |
| 6 | D | passive | DRAIN terminal (pins 5, 6, 7 and 8 are all listed as DRAIN in the pinning table); drain-source breakdown voltage V(BR)DSS is 30 V. |
| 7 | D | passive | DRAIN terminal (pins 5, 6, 7 and 8 are all listed as DRAIN in the pinning table); drain-source breakdown voltage V(BR)DSS is 30 V. |
| 8 | D | passive | DRAIN terminal (pins 5, 6, 7 and 8 are all listed as DRAIN in the pinning table); drain-source breakdown voltage V(BR)DSS is 30 V. |
