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

IRF7404TRPBF 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 | S | passive | Source of the P-channel MOSFET (pin 1 of the SO-8, shown as S on the Top View). |
| 2 | S | passive | Source of the P-channel MOSFET (pin 2 of the SO-8, shown as S on the Top View). |
| 3 | S | passive | Source of the P-channel MOSFET (pin 3 of the SO-8, shown as S on the Top View). |
| 4 | G | input | Gate of the P-channel MOSFET; gate-to-source voltage is rated ±12 V maximum. |
| 5 | D | passive | Drain of the P-channel MOSFET; VDSS is -20 V, with continuous drain current of -6.7 A at TA = 25°C. |
| 6 | D | passive | Drain of the P-channel MOSFET; VDSS is -20 V, with continuous drain current of -6.7 A at TA = 25°C. |
| 7 | D | passive | Drain of the P-channel MOSFET; VDSS is -20 V, with continuous drain current of -6.7 A at TA = 25°C. |
| 8 | D | passive | Drain of the P-channel MOSFET; VDSS is -20 V, with continuous drain current of -6.7 A at TA = 25°C. |
