KPY3203D from KIA Semicon Tech, in a DFN-8(5x6). 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 | Source | passive | Source terminal of the P-channel MOSFET, listed in the datasheet pin function table with pins 2 and 3 as Source. |
| 2 | Source | passive | Source terminal of the P-channel MOSFET, listed in the datasheet pin function table with pins 1 and 3 as Source. |
| 3 | Source | passive | Source terminal of the P-channel MOSFET, listed in the datasheet pin function table with pins 1 and 2 as Source. |
| 4 | Gate | input | Gate terminal of the P-channel MOSFET; the gate-source voltage is limited to ±20 V per the absolute maximum ratings. |
| 5 | Drain | passive | Drain terminal of the P-channel MOSFET, grouped with pins 6, 7 and 8 as Drain in the pin function table. |
| 6 | Drain | passive | Drain terminal of the P-channel MOSFET, grouped with pins 5, 7 and 8 as Drain in the pin function table. |
| 7 | Drain | passive | Drain terminal of the P-channel MOSFET, grouped with pins 5, 6 and 8 as Drain in the pin function table. |
| 8 | Drain | passive | Drain terminal of the P-channel MOSFET, grouped with pins 5, 6 and 7 as Drain in the pin function table. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
