**TF** · MOSFETs · SOT-23

TF2306 from TF, 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 (VGS, absolute maximum). |
| 2 | SOURCE | passive | Source of the N-channel MOSFET; the maximum body-diode continuous current is 2.5 A (IS). |
| 3 | DRAIN | passive | Drain of the N-channel MOSFET; drain-source voltage is rated at 30 V (VDS) with continuous drain current of 3.6 A at TA=25°C. |
