# TPSP3003-02XTG

**TECH PUBLIC** · Electrostatic And Surge Protection (TVS/ESD) · SOT-353

TPSP3003-02XTG 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 connection; the datasheet pin configuration shows this pin as NC. |
| 2 | GND | power_in | Ground reference connected to the TVS diode of the array. |
| 3 | VCC | power_in | Supply-side steering diode connection with a reverse working voltage of 5V max. |
| 4 | IO | passive | Protected data line input with ESD protection of ±20kV air and ±15kV contact and 0.35 pF typical IO-to-IO capacitance. |
| 5 | IO | passive | Protected data line input with ESD protection of ±20kV air and ±15kV contact and 0.35 pF typical IO-to-IO capacitance. |
