# AO3415B

**TWGMC** · MOSFETs · SOT-23

AO3415B from TWGMC, 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 P-channel MOSFET; the datasheet gives a gate-source voltage rating of ±12 V. |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET; the datasheet gives no separate pin-specific limit and lists the device ratings as VDS = -20 V and ID = -5.5 A. |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET, rated for a drain-source voltage of -20 V and continuous drain current of -5.5 A (pulsed IDM -30 A). |

## CAD (KiCad official)

- Symbol: `AO3415B`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `ao3415b-etched.step` / `ao3415b-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ao3415b.step` / `ao3415b.glb` are the bare package body.
