TPNUP2114UPXV5T1G from TECH PUBLIC, in a SOT-553. 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 | VP | power_in | Positive supply/power line pin protected by the internal steering diodes and TVS; the datasheet gives a 5V reverse working voltage (any I/O pin to ground). |
| 2 | VN | power_in | Negative/ground reference pin of the ESD protection array; I/O ratings are specified to ground. |
| 3 | NC | unconnected | No internal connection. |
| 4 | I/O | passive | Protected data line with 0.35pF typ (0.6pF max) I/O-to-I/O capacitance and 5V reverse working voltage; ESD rated ±25kV air and ±20kV contact per IEC 61000-4-2. |
| 5 | I/O | passive | Protected data line with 0.35pF typ (0.6pF max) I/O-to-I/O capacitance and 5V reverse working voltage; ESD rated ±25kV air and ±20kV contact per IEC 61000-4-2. |
