**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-363

TPNUP4114UCW1T2G from TECH PUBLIC, in a SOT-363. 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 | CH1 | passive | ESD-protected high-speed I/O channel 1, steered by diodes to VP and VN, with 1.5pF typical channel capacitance and ±18kV air / ±14kV contact IEC 61000-4-2 protection. |
| 2 | VN | power_in | Negative supply/ground reference pin (GND) of the TVS array, with reverse stand-off of 5V max measured from pin 5 to pin 2. |
| 3 | CH2 | passive | ESD-protected high-speed I/O channel 2, steered by diodes to VP and VN, with 1.5pF typical channel capacitance and ±18kV air / ±14kV contact IEC 61000-4-2 protection. |
| 4 | CH4 | passive | ESD-protected high-speed I/O channel 4, steered by diodes to VP and VN, with 1.5pF typical channel capacitance and ±18kV air / ±14kV contact IEC 61000-4-2 protection. |
| 5 | VP | power_in | Positive supply (VDD) pin of the TVS array, with operating supply voltage (VDD-GND) of 6V max and 5V reverse stand-off voltage. |
| 6 | CH3 | passive | ESD-protected high-speed I/O channel 3, steered by diodes to VP and VN, with 1.5pF typical channel capacitance and ±18kV air / ±14kV contact IEC 61000-4-2 protection. |
