ESDA25W5 from TECH PUBLIC, 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 | IO1 | passive | TVS protected I/O line 1, clamped to pin 2 (GND) with 24V max reverse working voltage and ±15kV air / ±8kV contact ESD protection. |
| 2 | GND | power_in | Common ground/cathode node of the 4-line TVS array that all I/O diodes reference. |
| 3 | IO2 | passive | TVS protected I/O line 2, clamped to pin 2 (GND) with 24V max reverse working voltage and ±15kV air / ±8kV contact ESD protection. |
| 4 | IO3 | passive | TVS protected I/O line 3, clamped to pin 2 (GND) with 24V max reverse working voltage and ±15kV air / ±8kV contact ESD protection. |
| 5 | IO4 | passive | TVS protected I/O line 4, clamped to pin 2 (GND) with 24V max reverse working voltage and ±15kV air / ±8kV contact ESD protection. |
