# TPNUP4102XV6T1G

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT563

TPNUP4102XV6T1G from TECH PUBLIC, in a SOT563. 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/O1 | passive | Bi-directional TVS channel line (pin 1) clamped to the common pins 2 and 5, with 12V reverse working voltage and 25V max clamping at 3A (8/20µs). |
| 2 | GND | power_in | Common return of the TVS array, tied internally to pin 5 and connected to ground. |
| 3 | I/O2 | passive | Bi-directional TVS channel line (pin 3) clamped to the common pins 2 and 5, with 12V reverse working voltage and 25V max clamping at 3A (8/20µs). |
| 4 | I/O3 | passive | Bi-directional TVS channel line (pin 4) clamped to the common pins 2 and 5, with 12V reverse working voltage and 25V max clamping at 3A (8/20µs). |
| 5 | GND | power_in | Common return of the TVS array, tied internally to pin 2 and connected to ground. |
| 6 | I/O4 | passive | Bi-directional TVS channel line (pin 6) clamped to the common pins 2 and 5, with 12V reverse working voltage and 25V max clamping at 3A (8/20µs). |
