IRF7389TRPBF 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 (30V, 0.029 ohm RDS(on) max at VGS=10V). |
| 2 | G1 | input | Gate of the N-channel MOSFET, rated ±20V VGS maximum. |
| 3 | S2 | passive | Source of the P-channel MOSFET (-30V, 0.058 ohm RDS(on) max at VGS=-10V). |
| 4 | G2 | input | Gate of the P-channel MOSFET, rated ±20V VGS maximum. |
| 5 | D2 | passive | Drain of the P-channel MOSFET, tied with pin 6; the -30V VDS device with -5.3A continuous drain current at TA=25°C. |
| 6 | D2 | passive | Drain of the P-channel MOSFET, tied with pin 5. |
| 7 | D1 | passive | Drain of the N-channel MOSFET, tied with pin 8; the 30V VDS device with 7.3A continuous drain current at TA=25°C. |
| 8 | D1 | passive | Drain of the N-channel MOSFET, tied with pin 7. |
