TPAZ5425-01F from TECH PUBLIC, in a DFN1006-2. 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 | Pin 1 | passive | One terminal of the bidirectional TVS diode protecting one data or power line; datasheet ratings are referenced Pin1-Pin2, with reverse working voltage of 5 V max and breakdown voltage of 6.5 V min at IT = 1 mA. |
| 2 | Pin 2 | passive | Other terminal of the bidirectional TVS diode protecting one data or power line; reverse leakage is specified at VRWM = 5.0 V (Pin2-Pin1) with 0.08 µA max, and the device is rated for operating voltage of ±5 V. |
