NUP4114UCW1T2G from UMW, 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 | I/O | bidirectional | ESD-protected data/power line I/O, rated for IEC 61000-4-2 ±15kV contact and ±20kV air discharge, with a working peak reverse voltage VRWM of 5V. |
| 2 | GND | power_in | Ground reference for the protection clamps; junction capacitance is specified to IO-to-GND at VR=0V, f=1MHz. |
| 3 | I/O | bidirectional | ESD-protected data/power line I/O, rated for IEC 61000-4-2 ±15kV contact and ±20kV air discharge, with a working peak reverse voltage VRWM of 5V. |
| 4 | I/O | bidirectional | ESD-protected data/power line I/O, rated for IEC 61000-4-2 ±15kV contact and ±20kV air discharge, with a working peak reverse voltage VRWM of 5V. |
| 5 | VCC | power_in | Supply pin labeled VCC on the pinning diagram; the datasheet gives no voltage limit or function for this pin. |
| 6 | I/O | bidirectional | ESD-protected data/power line I/O, rated for IEC 61000-4-2 ±15kV contact and ±20kV air discharge, with a working peak reverse voltage VRWM of 5V. |
