# FS3415

**FOSAN** · MOSFETs · SOT-23-3L

FS3415 from FOSAN, in a SOT-23-3L. 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 of the P-channel MOSFET, rated for VGS of +/-12 V maximum with 2.0 kV HBM ESD protection. |
| 2 | S | passive | Source of the P-channel MOSFET, carrying the continuous drain current of up to -5 A (pulsed -23 A) at TA = 25 C. |
| 3 | D | passive | Drain of the P-channel MOSFET, rated for a drain-source voltage of -20 V and a continuous drain current of -5 A (pulsed -23 A) at TA = 25 C. |

## CAD (KiCad official)

- Symbol: `FS3415`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3L (KiCad packages3D, STEP)
- 3D model files: `fs3415-etched.step` / `fs3415-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `fs3415.step` / `fs3415.glb` are the bare package body.
