**Infineon Technologies** · MOSFETs · SO-8

IRF7317TRPBF from Infineon Technologies, in a SO-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 the N-channel MOSFET (VDSS 20V, RDS(on) 0.029Ω). |
| 2 | G1 | input | Gate of the N-channel MOSFET, with a maximum gate-source voltage of ±12V. |
| 3 | S2 | passive | Source of the P-channel MOSFET (VDSS -20V, RDS(on) 0.058Ω). |
| 4 | G2 | input | Gate of the P-channel MOSFET, with a maximum gate-source voltage of ±12V. |
| 5 | D2 | passive | Drain of the P-channel MOSFET, which is tied to pin 6 and is rated for -5.3A continuous at TA=25°C. |
| 6 | D2 | passive | Drain of the P-channel MOSFET, which is tied to pin 5 and is rated for -5.3A continuous at TA=25°C. |
| 7 | D1 | passive | Drain of the N-channel MOSFET, which is tied to pin 8 and is rated for 6.6A continuous at TA=25°C. |
| 8 | D1 | passive | Drain of the N-channel MOSFET, which is tied to pin 7 and is rated for 6.6A continuous at TA=25°C. |
