ESD73031N-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 | Pin 1 is one terminal of the single bidirectional protected line, which is rated for a 5.0 V maximum reverse working voltage (VRWM) and ±30 kV contact-discharge ESD per IEC61000-4-2. |
| 2 | Pin2 | passive | Pin 2 is the other terminal of the single bidirectional protected line, which is rated for a 5.0 V maximum reverse working voltage (VRWM) and 11 A peak pulse current (8/20 µs) per IEC61000-4-5. |
