USBLC6-4SC6

STMicroelectronics · ESD And Surge Protection (TVS/ESD) · SOT-23-6L

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.
