AQ4337-01ETG 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 | One of the two terminals of this bidirectional TVS; the datasheet gives a 5V reverse standoff voltage, 0.25pF typical capacitance at 0V, and clamp and ESD ratings measured I/O to GND, but does not state which terminal is I/O and which is GND. |
| 2 | 2 | passive | The other of the two terminals of this bidirectional TVS; the datasheet gives a 5V reverse standoff voltage, 0.25pF typical capacitance at 0V, and clamp and ESD ratings measured I/O to GND, but does not state which terminal is I/O and which is GND. |
