RW1A025APT2CR from ROHM Semicon, in a SOT-563. 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 | Drain | passive | Drain terminal of the silicon P-channel MOSFET, rated for 12 V drain-source voltage (VDSS) and 2.5 A continuous drain current (ID). |
