**XIN FEI HONG** · MOSFETs · SOT-23

FH3415P from XIN FEI HONG, 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 | G | input | Gate; controls the P-channel switch, with VGSS limited to ±10 V and threshold VGS(th) of -0.4 to -1.0 V. |
