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

USBLC6-2SC6-FS from FUXINSEMI, in a SOT-23-6L. 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 I/O line 1 (pins 1 and 6 are the same channel); 8/20µs Ipp 5.5A I/O-GND, 0.7 pF typ I/O-GND capacitance. |
| 2 | GND | power_in | Ground reference for the TVS array; I/O-GND peak pulse power 88 W (8/20µs). |
| 3 | I/O2 | passive | ESD-protected I/O line 2 (pins 3 and 4 are the same channel); ±30 kV air/contact ESD per IEC 61000-4-2. |
| 4 | I/O2 | passive | ESD-protected I/O line 2 (connected internally with pin 3); reverse working voltage 5 V max. |
| 5 | Vcc | power_in | Supply-rail protection pin with internal TVS to GND; VCC-GND 8/20µs Ipp 8 A, peak pulse power 120 W. |
| 6 | I/O1 | passive | ESD-protected I/O line 1 (connected internally with pin 1); I/O-I/O capacitance 0.35 pF typ. |
