IRF5803TRPBF-TP from TECH PUBLIC, in a SOT-23-6. 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 | D | passive | Drain of the P-channel MOSFET (pin 1, marked by the dot), rated VDS -40 V and continuous ID -4 A at TC=25°C; connected to the other drain pins. |
| 2 | D | passive | Drain of the P-channel MOSFET, rated VDS -40 V and continuous ID -4 A at TC=25°C; connected to the other drain pins. |
| 3 | G | input | Gate of the P-channel MOSFET, with absolute maximum gate-source voltage of ±20 V and threshold VGS(th) of -1.0 V min to -3.0 V max. |
| 4 | S | passive | Source of the P-channel MOSFET, with continuous body-diode source current of -4 A max. |
| 5 | D | passive | Drain of the P-channel MOSFET, rated VDS -40 V with RDS(on) of 85 mΩ max at VGS=-10 V; connected to the other drain pins. |
| 6 | D | passive | Drain of the P-channel MOSFET, rated VDS -40 V with RDS(on) of 85 mΩ max at VGS=-10 V; connected to the other drain pins. |
