# TPNUP2201MR6T1G

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-23-6

TPNUP2201MR6T1G 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 I/O line 1, rated for 5V reverse working voltage (VRWM) to ground and 0.6 pF typical capacitance between I/O pins. |
| 2 | VN | power_in | Negative reference (ground) pin of the TVS array; I/O pins are specified relative to ground. |
| 3 | NC | unconnected | No connection. |
| 4 | NC | unconnected | No connection. |
| 5 | VP | passive | Positive reference node of the steering-diode array, connected to the internal TVS diode; the datasheet does not give a supply voltage rating for it. |
| 6 | I/O | passive | ESD-protected I/O line 2, rated for 5V reverse working voltage (VRWM) to ground and 0.6 pF typical capacitance between I/O pins. |
