TPSP3003-02JTG from TECH PUBLIC, in a SOT-353. 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 | NC | unconnected | No internal connection, labeled NC in the SOT353 pin configuration diagram. |
| 2 | GND | power_in | Ground reference of the TVS array, connected to the central Zener diode in the pin configuration diagram. |
| 3 | VCC | power_in | Supply/rail pin of the steering-diode array, with a reverse working voltage of 5V max and breakdown voltage of 6V min at 1mA. |
| 4 | IO | passive | Protected data/signal line (IO) with ESD protection to ±20kV air and ±15kV contact per IEC 61000-4-2 and 0.35pF typical IO-to-IO capacitance. |
| 5 | IO | passive | Protected data/signal line (IO) with ESD protection to ±20kV air and ±15kV contact per IEC 61000-4-2 and 0.35pF typical IO-to-IO capacitance. |
