NSQA6V8AW5T2 from Leiditech, in a SOT-353. 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 1, steered to the common pin 2 through the lower left diode; working voltage 5V, breakdown 6.1V min at 1mA. |
| 2 | GND | power_in | Common pin that joins the diode array center node, serving as the ground reference for the protected lines. |
| 3 | I/O2 | passive | ESD-protected line 2, steered to the common pin 2 through the lower right diode; working voltage 5V, breakdown 6.1V min at 1mA. |
| 4 | I/O3 | passive | ESD-protected line 3 (upper right diode); working voltage 5V, rated for ±30kV air and ±25kV contact ESD per IEC 61000-4-2. |
| 5 | I/O4 | passive | ESD-protected line 4 (upper left diode); working voltage 5V, rated for ±30kV air and ±25kV contact ESD per IEC 61000-4-2. |
