**Cmos(广东场效应半导体)** · IC · SOT-23-3L

CMN3400ZM from Cmos(广东场效应半导体), 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 | Gate | input | Gate terminal of the N-channel MOSFET, rated for gate-source voltage VGS of ±20V, and the datasheet notes operation with gate voltages as low as 1.5V. |
