# QM2416K

**KUU** · MOSFETs · SOT-23

QM2416K from KUU, in a SOT-23. 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; the datasheet limits the gate-source voltage to VGS ±12 V. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET; the datasheet rates the continuous source-drain (diode conduction) current IS at 0.6 A. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; the datasheet rates the drain-source voltage VDS at 20 V and the continuous drain current ID at 6 A. |
