LXES15AAA1-153 from Leiditech, 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 | Bidirectional single-line ESD protection terminal connected to the signal line, with 0.05 pF typ. capacitance and 5 V max continuous operating voltage. |
| 2 | 2 | passive | Second terminal of the bidirectional ESD suppressor, connected to GND or the signal line (symmetric device), rated for IEC61000-4-2 8 kV contact and 15 kV air discharge. |
