AQ1003-01ETG from Littelfuse, in a SOD-882. 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 | 1 | passive | The datasheet pinout shows pin 1 as one of the two SOD882 terminals (pin-1 indicator on the top view) but does not say whether it is the I/O or ground side; the device is rated at 5.0 V reverse standoff (VRWM) with 100 nA max reverse leakage at 5 V. |
| 2 | 2 | passive | The datasheet pinout shows pin 2 as the other SOD882 terminal but does not say whether it is the I/O or ground side; the device is rated at 5.0 V reverse standoff (VRWM) with 100 nA max reverse leakage at 5 V. |
