**TF** · MOSFETs · SOT-23

TF3415 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 terminal of the P-channel MOSFET; gate-source voltage is rated at ±10 V maximum (VGS) per the absolute maximum ratings. |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET; continuous source-drain diode current is rated at -1.25 A (IS) per the maximum ratings. |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET; drain-source voltage is rated at -15 V (VDS) with continuous drain current of -4.3 A (ID) per the maximum ratings. |
