# USBLC6-2SC6-MS

**MSKSEMI** · ESD And Surge Protection (TVS/ESD) · SOT-23-6

USBLC6-2SC6-MS from MSKSEMI, in a SOT-23-6. 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 high-speed I/O channel 1 (pins 1 and 6 are the same channel), with 0.8pF typical I/O-to-GND capacitance and 5.0V max reverse working voltage. |
| 2 | GND | power_in | Ground reference for the ESD protection diodes. |
| 3 | I/O2 | passive | ESD-protected high-speed I/O channel 2 (pins 3 and 4 are the same channel), with 0.8pF typical I/O-to-GND capacitance and 5.0V max reverse working voltage. |
| 4 | I/O2 | passive | ESD-protected high-speed I/O channel 2, connected internally to pin 3, with IEC 61000-4-2 protection of ±30kV air and ±30kV contact. |
| 5 | VBUS | power_in | Supply/VBUS-side clamp connection of the diode array, labeled VBUS in the symbol and VDD in the clamping-voltage specs, with 5.0V max reverse working voltage. |
| 6 | I/O1 | passive | ESD-protected high-speed I/O channel 1, connected internally to pin 1, with IEC 61000-4-2 protection of ±30kV air and ±30kV contact. |
