# K2SK3018-7-F

**KUU** · MOSFETs · SOT-23

K2SK3018-7-F 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 of the N-channel MOSFET; gate-source voltage is rated at ±20 V (VGSS). |
| 2 | SOURCE | passive | Source of the N-channel MOSFET; the datasheet gives drain-source breakdown V(BR)DSS of 30 V minimum at VGS = 0 V, ID = 10 µA. |
| 3 | DRAIN | passive | Drain of the N-channel MOSFET; the ratings table gives continuous drain current 0.1 A and power dissipation 0.2 W (Ta = 25°C). |
