AQ3118-01ETG
Littelfuse · ESD Protection Devices · SOD-882
AQ3118-01ETG 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 | Bidirectional TVS diode terminal 1 (I/O), protects the data line against ESD up to ±10kV contact and ±15kV air per IEC 61000-4-2, with reverse standoff voltage of 18V. |
| 2 | 2 | passive | Bidirectional TVS diode terminal 2 (I/O or GND), symmetric with pin 1 given the back-to-back configuration, with 0.3pF capacitance at VR=0V. |
