USBLC6-4SC6 from STMicroelectronics, in a SOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | bidirectional | I/O data line with ESD protection; clamping voltage 12 V at 1 A and 17 V at 5 A surge current (8/20 µs) to ground with line capacitance of 3 pF typical. |
| 2 | GND | power_in | Ground pin; common return path for ESD protection circuits. |
| 3 | I/O2 | bidirectional | I/O data line with ESD protection; clamping voltage 12 V at 1 A and 17 V at 5 A surge current (8/20 µs) to ground with line capacitance of 3 pF typical. |
| 4 | I/O3 | bidirectional | I/O data line with ESD protection; clamping voltage 12 V at 1 A and 17 V at 5 A surge current (8/20 µs) to ground with line capacitance of 3 pF typical. |
| 5 | VBUS | power_in | VBUS power line (5 V nominal) with internal Zener ESD protection; breakdown voltage 6-10 V at 1 mA with forward voltage 0.86 V at 10 mA. |
| 6 | I/O4 | bidirectional | I/O data line with ESD protection; clamping voltage 12 V at 1 A and 17 V at 5 A surge current (8/20 µs) to ground with line capacitance of 3 pF typical. |
