# AO4266E

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

AO4266E 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 terminal of the 60V N-channel MOSFET; the datasheet gives VDS of 60V and VGS of ±20V for the device. |
| 2 | S | passive | Source terminal of the 60V N-channel MOSFET; the datasheet gives VDS of 60V and VGS of ±20V for the device. |
| 3 | S | passive | Source terminal of the 60V N-channel MOSFET; the datasheet gives VDS of 60V and VGS of ±20V for the device. |
| 4 | G | input | Gate terminal; the datasheet specifies a gate-source voltage limit of ±20V and a logic-level gate drive (RDS(ON) < 18mΩ at VGS=4.5V). |
| 5 | D | passive | Drain terminal of the 60V N-channel MOSFET, rated 11A continuous at VGS=10V. |
| 6 | D | passive | Drain terminal of the 60V N-channel MOSFET, rated 11A continuous at VGS=10V. |
| 7 | D | passive | Drain terminal of the 60V N-channel MOSFET, rated 11A continuous at VGS=10V. |
| 8 | D | passive | Drain terminal of the 60V N-channel MOSFET, rated 11A continuous at VGS=10V. |
