**Cmos** · MOSFETs · TO-252

CMD100N03 from Cmos, 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; controls the channel, with VGS rated at ±20 V maximum and a threshold of 1 V min to 3 V max at ID=250uA. |
| 2 | D | passive | Drain, the shortened centre lead, which is internally common with the exposed drain tab; VDS is rated at 30 V and continuous ID at 100 A at TC=25°C. |
| 3 | S | passive | Source; the continuous source (body-diode) current is rated at 100 A. |
