**TECH PUBLIC** · ESD Protection Devices · SOT-23-6

TPNUP2114UCMR6T1G 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 | I/O | passive | ESD-protected data line (I/O) with 0.3pF I/O-to-I/O capacitance, reverse working voltage 5V max to ground. |
| 2 | VN | power_in | Negative reference (ground) pin of the TVS array, to which the I/O pins are clamped. |
| 3 | NC | unconnected | No connect pin. |
| 4 | NC | unconnected | No connect pin. |
| 5 | VP | power_in | Positive power-line reference pin protected by the array (one power line protected). |
| 6 | I/O | passive | ESD-protected data line (I/O) with 0.3pF I/O-to-I/O capacitance, reverse working voltage 5V max to ground. |
