**KY** · MOSFETs · SOT-23

KY2N7002K from KY, 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, with gate-source voltage rated at ±20 V (VGSS) in the maximum ratings. |
