ESDAULC6-1U2 from STMicroelectronics, in a 0201. 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 | K | passive | Cathode (pin 1, marked pad) connects to the protected data line or I/O, which has a 6 V min breakdown voltage at 1 mA, 3 V stand-off voltage and 0.8 pF typ line capacitance. |
| 2 | A | passive | Anode connects to ground as the return of the unidirectional TVS diode, which is rated for IEC 61000-4-2 ±8 kV contact and ±15 kV air discharge. |
