# AO4264E

**Alpha Omega Semicon** · MOSFETs · SOIC-8

AO4264E from Alpha Omega Semicon, in a SOIC-8. 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 | S | passive | Source; pin 1 is marked on the package and the datasheet shows pins 1-3 as source, with 10.5A to 13.5A continuous drain current rating (ID) and 4A max body-diode current. |
| 2 | S | passive | Source, tied to the same source terminal as pins 1 and 3. |
| 3 | S | passive | Source, tied to the same source terminal as pins 1 and 2. |
| 4 | G | input | Gate with ESD protection (typical HBM Class 2); gate-source voltage max ±20V and threshold 1.4V min to 2.4V max. |
| 5 | D | passive | Drain, connected to the same drain terminal as pins 6-8; drain-source voltage max 60V. |
| 6 | D | passive | Drain, connected to the same drain terminal as pins 5, 7 and 8. |
| 7 | D | passive | Drain, connected to the same drain terminal as pins 5, 6 and 8. |
| 8 | D | passive | Drain, connected to the same drain terminal as pins 5-7; pulsed drain current max 54A. |

## CAD (KiCad official)

- Symbol: `AO4264E`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `ao4264e-etched.step` / `ao4264e-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ao4264e.step` / `ao4264e.glb` are the bare package body.
