# TPUSBLC6-2SC6

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

TPUSBLC6-2SC6 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 | ESD-protected I/O line 1 (pins 1 and 6 are the same line); 0.8 pF typ, 1 pF max to GND, with a 0.35 pF typ I/O-to-I/O capacitance. |
| 2 | GND | power_in | Ground reference for the ESD protection diodes. |
| 3 | I/O2 | passive | ESD-protected I/O line 2 (pins 3 and 4 are the same line); rated for ±30kV IEC 61000-4-2 air and contact discharge. |
| 4 | I/O2 | passive | ESD-protected I/O line 2, internally tied to pin 3; reverse stand-off voltage 5V max. |
| 5 | VBUS | power_in | Supply/VBUS connection of the protection diode network; reverse stand-off voltage 5V max, breakdown 6V min to 9V max at 1mA. |
| 6 | I/O1 | passive | ESD-protected I/O line 1, internally tied to pin 1; clamping voltage 10V max at 1A and 15V max at 6A (8/20µs). |
