ESD5425E-6 from WILLSEMI(Will Semicon), in a SOT-23-6L. 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 | Data line I/O protected by the TVS array, rated for ±30kV contact discharge per IEC61000-4-2 and 25A (8/20μs) per IEC61000-4-5 to GND. |
| 2 | GND | power_in | Ground reference pin; the clamping and ESD ratings are specified for any I/O to GND. |
| 3 | I/O | bidirectional | Data line I/O protected by the TVS array, rated for ±30kV contact discharge per IEC61000-4-2 and 25A (8/20μs) per IEC61000-4-5 to GND. |
| 4 | I/O | bidirectional | Data line I/O protected by the TVS array, rated for ±30kV contact discharge per IEC61000-4-2 and 25A (8/20μs) per IEC61000-4-5 to GND. |
| 5 | VDD | power_in | Supply pin of the device; the datasheet specifies VDD floated during the I/O-to-GND junction capacitance test. |
| 6 | I/O | bidirectional | Data line I/O protected by the TVS array, rated for ±30kV contact discharge per IEC61000-4-2 and 25A (8/20μs) per IEC61000-4-5 to GND. |
