USBLC6-4SC6Y from STMicroelectronics, 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 data/signal line 1, clamped to GND and VBUS with low capacitance (3 pF typ) for USB D+/D- or similar high-speed line protection. |
| 2 | GND | power_in | Ground reference for the ESD protection device. |
| 3 | I/O2 | passive | ESD-protected data/signal line 2, clamped to GND and VBUS with low capacitance (3 pF typ) for USB D+/D- or similar high-speed line protection. |
| 4 | I/O3 | passive | ESD-protected data/signal line 3, clamped to GND and VBUS with low capacitance (3 pF typ) for USB D+/D- or similar high-speed line protection. |
| 5 | VBUS | power_in | VBUS supply line protected against ESD strikes, breakdown voltage 6 V typ (IR = 1 mA), clamping voltage 12 V max at IPP = 1 A, 8/20 µs. |
| 6 | I/O4 | passive | ESD-protected data/signal line 4, clamped to GND and VBUS with low capacitance (3 pF typ) for USB D+/D- or similar high-speed line protection. |
