CMD70N03D from Cmos(广东场效应半导体), 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, ESD protected, with a maximum gate-source voltage of ±16 V and a gate threshold of 1 V min to 3 V max at VDS=VGS, ID=250µA. |
| 2 | D | passive | Drain, the mounting tab, with a maximum drain-source voltage of 30 V and a continuous drain current of 70 A at TC=25℃ (pulsed 280 A). |
| 3 | S | passive | Source, which carries the 70 A continuous current at TC=25℃ and the body-diode continuous source current of 70 A. |
