IRLMS1503TRPBF from Infineon Technologies, 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, internally connected to the other drain pins (2, 5, 6); drain-to-source breakdown is 30V min and continuous drain current is 3.2A at TA=25°C. |
| 2 | D | passive | Drain, internally connected to the other drain pins (1, 5, 6); drain-to-source breakdown is 30V min and continuous drain current is 3.2A at TA=25°C. |
| 3 | G | input | Gate of the N-channel MOSFET; gate-to-source voltage is rated ±20V max and threshold voltage is 1.0V min. |
| 4 | S | passive | Source of the N-channel MOSFET; body diode continuous source current is 1.7A max. |
| 5 | D | passive | Drain, internally connected to the other drain pins (1, 2, 6); RDS(on) is 0.100 ohm max at VGS=10V, ID=2.2A. |
| 6 | D | passive | Drain, internally connected to the other drain pins (1, 2, 5); RDS(on) is 0.100 ohm max at VGS=10V, ID=2.2A. |
