**Cmos** · MOSFETs · SOT-23-3L

CMN1029M from Cmos, in a SOT-23-3L. 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 of the P-channel MOSFET; gate-source voltage limited to ±20V with threshold VGS(th) of -1.0V to -3.0V. |
| 2 | S | passive | Source of the P-channel MOSFET; drain-source voltage up to -100V and continuous drain current of -1.5A. |
| 3 | D | passive | Drain of the P-channel MOSFET; rated -100V drain-source with RDS(on) of 200mΩ max at VGS=-10V and pulsed current of -5A. |

## CAD (KiCad official)

- Symbol: `CMN1029M`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3L (KiCad packages3D, STEP)
- 3D model files: `cmn1029m-etched.step` / `cmn1029m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cmn1029m.step` / `cmn1029m.glb` are the bare package body.
