ESD5651N-2 from WILLSEMI(Will Semicon), in a DFN1006-2L. 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 | Pin1 | passive | One terminal of the bi-directional TVS; the device has a reverse stand-off voltage of ±4.5V max and gives ESD protection up to ±30kV (contact and air discharge) per IEC61000-4-2. |
| 2 | Pin2 | passive | The other terminal of the bi-directional TVS; the device has a reverse stand-off voltage of ±4.5V max and gives ESD protection up to ±30kV (contact and air discharge) per IEC61000-4-2. |
