ESDALC6V1-5P6

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.
