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

TPD4E1U06DBVR-TP 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 | Pin 1 is labeled D2- in the SOT23-6 pin diagram and is a TVS-protected I/O channel with 0.6pF typical capacitance to GND, 5.5V max working voltage and ±15kV contact ESD rating. |
| 2 | GND | power_in | Ground reference for the TVS diode array, to which all I/O channels clamp. |
| 3 | D2+ | passive | TVS-protected I/O channel D2+ with 0.6pF typical capacitance to GND, 5.5V max working voltage and ±15kV contact ESD rating. |
| 4 | D2- | passive | TVS-protected I/O channel D2- with 0.6pF typical capacitance to GND, 5.5V max working voltage and ±15kV contact ESD rating. |
| 5 | NC | unconnected | No connection. |
| 6 | D1- | passive | TVS-protected I/O channel D1- with 0.6pF typical capacitance to GND, 5.5V max working voltage and ±15kV contact ESD rating. |
