**STMicroelectronics** · ESD And Surge Protection (TVS/ESD) · SOT-666

ESDALC6V1-5P6 from STMicroelectronics, in a SOT-666. 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 | I/O1 | passive | ESD-protected line with diode-array clamp to GND, rated 8 kV contact and 15 kV air discharge per IEC 61000-4-2, with 12 pF typical capacitance and 5 V maximum stand-off voltage. |
| 2 | GND | power_in | Common ground node of the diode array, to which all protected lines clamp. |
| 3 | I/O2 | passive | ESD-protected line with diode-array clamp to GND, rated 8 kV contact and 15 kV air discharge per IEC 61000-4-2, with 12 pF typical capacitance and 5 V maximum stand-off voltage. |
| 4 | I/O3 | passive | ESD-protected line with diode-array clamp to GND, rated 8 kV contact and 15 kV air discharge per IEC 61000-4-2, with 12 pF typical capacitance and 5 V maximum stand-off voltage. |
| 5 | I/O4 | passive | ESD-protected line with diode-array clamp to GND, rated 8 kV contact and 15 kV air discharge per IEC 61000-4-2, with 12 pF typical capacitance and 5 V maximum stand-off voltage. |
