# TPUSBLC6-4SC6

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

TPUSBLC6-4SC6 from TECH PUBLIC, 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 | Protected data line I/O pin (steering diodes to the rails), 0.35 pF typ between I/O pins, 5 V max reverse working voltage to ground. |
| 2 | GND | power_in | Ground reference pin at the bottom rail of the TVS array; I/O pins are rated 5 V max reverse working voltage to ground. |
| 3 | I/O2 | passive | Protected data line I/O pin (steering diodes to the rails), 0.35 pF typ between I/O pins, 5 V max reverse working voltage to ground. |
| 4 | I/O3 | passive | Protected data line I/O pin (steering diodes to the rails), 0.35 pF typ between I/O pins, 5 V max reverse working voltage to ground. |
| 5 | VBUS | power_in | Power line protection pin at the top rail of the array, where the central TVS diode clamps to ground (datasheet states protection of one power line). |
| 6 | I/O4 | passive | Protected data line I/O pin (steering diodes to the rails), 0.35 pF typ between I/O pins, 5 V max reverse working voltage to ground. |
