ESDALC6V1-1U2 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 | Pin 1 | passive | Pin 1 is the marked pin used for orientation at placement (the datasheet states only pin 1 marking should be used to orient the part), and it is available in different forms on the ST0201 package. |
| 2 | Pin 2 | passive | Pin 2 is the second terminal of this unidirectional single-line TVS diode, which protects a data line or I/O port against ESD with a breakdown voltage VBR of 6.1 V min. and a line capacitance of 12 pF typ. at 0 V. |
