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

TPE4106RS6 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 | D2- | passive | ESD-protected line labelled D2- on the pin diagram; uni-directional TVS channel to GND, 0.6pF typical I/O to GND, 5.5V reverse working voltage. |
| 2 | GND | power_in | Ground reference for the TVS diode array; all I/O channels clamp to this pin. |
| 3 | D2+ | passive | ESD-protected line labelled D2+ on the pin diagram; uni-directional TVS channel to GND, 0.6pF typical I/O to GND, 5.5V reverse working voltage. |
| 4 | D2- | passive | ESD-protected line labelled D2- on the pin diagram; uni-directional TVS channel to GND, 0.6pF typical I/O to GND, 5.5V reverse working voltage. |
| 5 | NC | unconnected | No connection. |
| 6 | D1- | passive | ESD-protected line labelled D1- on the pin diagram; uni-directional TVS channel to GND, 0.6pF typical I/O to GND, 5.5V reverse working voltage. |
