BORN · ESD And Surge Protection (TVS/ESD) · 0402
0402ESDA-18N from BORN, 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 | T1 | passive | First terminal of the bi-directional ESD suppressor, which can connect to either the protected signal line or ground because the part is not polarized, with a 1.5pF typ capacitance and <1nA leakage at 18V working voltage. |
| 2 | T2 | passive | Second terminal of the bi-directional ESD suppressor, interchangeable with the first terminal, which clamps ESD at 50V (Vc) with a 100V trigger voltage (Vv ±30%). |
