NUP4114UCLW1T2G 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 | IO | passive | ESD-protected data line I/O; I/O-to-GND junction capacitance 0.6pF typical, 0.7pF max at VR=0V, f=1MHz. |
| 2 | GND | power_in | Ground reference for the ESD protection diodes; connects to the common return of the steering diodes and Zener. |
| 3 | IO | passive | ESD-protected data line I/O; protects up to 4 data lines with I/O-to-I/O capacitance 0.3pF typical, 0.5pF max. |
| 4 | IO | passive | ESD-protected data line I/O rated for IEC 61000-4-2 ±25kV air and ±20kV contact discharge. |
| 5 | VCC | power_in | Power line protection pin; reverse working voltage 5.5V max, breakdown voltage 6V min to 9.5V max at IT=1mA. |
| 6 | IO | passive | ESD-protected data line I/O; clamping voltage 10V max at IPP=4.5A and 14V max at IPP=8A (8/20µs). |
