**Siliup** · MOSFETs · TO-252

SP30N03ATH from Siliup, in a TO-252. 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 | G | input | Gate terminal of the 30V N-channel MOSFET; the absolute maximum gate-source voltage is VGS ±20 V. |
| 2 | D | passive | Drain terminal of the MOSFET; the absolute maximum drain-source voltage is VDS 30 V and continuous drain current is 110 A at TC=25℃. |
| 3 | S | passive | Source terminal of the MOSFET, the reference for gate drive; the datasheet gives no separate pin-level limit for it. |
