AOSS21311C from Alpha Omega Semicon, in a SOT-23-3. 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; controls the P-channel MOSFET with VGS rated ±20V max and typical HBM Class 1C ESD protection. |
| 2 | S | passive | Source; connects to the supply side of the load switch, with continuous drain current rated -4.3A at TA=25°C. |
| 3 | D | passive | Drain; drain-source voltage rated -30V max with pulsed drain current of -17A. |
