# AO3413

**Alpha Omega Semicon** · MOSFETs · SOT-23

AO3413 from Alpha Omega Semicon, 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; the datasheet gives a maximum gate-source voltage of ±8V and a threshold of -0.4V min / -1V max at ID=-250µA, with RDS(ON) specified down to VGS=-1.8V. |
| 2 | S | passive | Source of the P-channel MOSFET; the maximum drain-source voltage is -20V and the body-diode continuous current is -1.4A max. |
| 3 | D | passive | Drain; the datasheet gives VDS=-20V, continuous ID=-3A at TA=25°C and pulsed IDM=-15A. |

## CAD (KiCad official)

- Symbol: `AO3413`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `ao3413-etched.step` / `ao3413-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ao3413.step` / `ao3413.glb` are the bare package body.
