TPESD0402G18V from TECH PUBLIC, in a 0402. 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 | 1 | passive | Terminal 1 of the bidirectional single-line ESD suppressor, connected to the protected signal line or to GND since the device is not polarized; rated ±15 kV air and ±8 kV contact per IEC 61000-4-2. |
| 2 | 2 | passive | Terminal 2 of the bidirectional single-line ESD suppressor, connected to the protected signal line or to GND since the device is not polarized; rated ±15 kV air and ±8 kV contact per IEC 61000-4-2. |
