ESDA6V1W5-5 from WILLSEMI Will Semicon, in a SOT-353. 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 | I/O | bidirectional | Protected signal line clamped just above the logic supply for positive transients and to a diode drop below ground for negative transients, with ±30kV contact ESD protection per IEC61000-4-2 and 9A (8/20μs) surge per IEC61000-4-5. |
| 2 | GND | power_in | Ground reference pin for the TVS array; negative transients are clamped to a diode drop below this ground. |
| 3 | I/O | bidirectional | Protected signal line clamped just above the logic supply for positive transients and to a diode drop below ground for negative transients, with ±30kV contact ESD protection per IEC61000-4-2 and 9A (8/20μs) surge per IEC61000-4-5. |
| 4 | I/O | bidirectional | Protected signal line clamped just above the logic supply for positive transients and to a diode drop below ground for negative transients, with ±30kV contact ESD protection per IEC61000-4-2 and 9A (8/20μs) surge per IEC61000-4-5. |
| 5 | I/O | bidirectional | Protected signal line clamped just above the logic supply for positive transients and to a diode drop below ground for negative transients, with ±30kV contact ESD protection per IEC61000-4-2 and 9A (8/20μs) surge per IEC61000-4-5. |
