TPAZ5A25-02R.R7G from TECH PUBLIC, in a SOT-523. 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 | Protected line connected through a bi-directional TVS diode to pin 3, with reverse working voltage 5 V max and breakdown voltage 6.5 to 8.5 V at 1 mA. |
| 2 | I/O2 | passive | Protected line connected through a bi-directional TVS diode to pin 3, with reverse working voltage 5 V max and breakdown voltage 6.5 to 8.5 V at 1 mA. |
| 3 | COMMON | passive | Common node of both TVS diodes, with junction capacitance of 15 pF typical (20 pF max) to pins 1 and 2 at VR = 0 V and 1 MHz. |
