**onsemi** · ESD Protection Devices · TSOP-6

NUP2114UCMR6T1G from onsemi, in a TSOP-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 | Protected high-speed data line input/output with 0.8 pF typical capacitance to GND (VN) and 5 V working reverse voltage. |
| 2 | VN | power_in | Negative (ground) reference of the uni-directional protection diodes; surge current is returned from VP (pin 5) to this pin (pin 5 to pin 2). |
| 3 | NC | unconnected | No connection. |
| 4 | NC | unconnected | No connection. |
| 5 | VP | passive | Positive rail connection of the protection diodes (5 V stand-off), used as the surge test reference to pin 2 with IPP up to 12 A (8x20 µs). |
| 6 | I/O | passive | Protected high-speed data line input/output with 0.8 pF typical capacitance to GND (VN) and 5 V working reverse voltage. |
