TPSMS05CT1G from TECH PUBLIC, in a SOT-23-6. 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 | TVS-protected line 1 (one of five channels), clamping to GND with VRWM 5V max and ±30kV ESD rating. |
| 2 | GND | power_in | Common ground rail of the array that all five TVS diodes reference. |
| 3 | I/O2 | passive | TVS-protected line 2 (one of five channels), clamping to GND with VRWM 5V max and ±30kV ESD rating. |
| 4 | I/O3 | passive | TVS-protected line 3 (one of five channels), clamping to GND with VRWM 5V max and ±30kV ESD rating. |
| 5 | I/O4 | passive | TVS-protected line 4 (one of five channels), clamping to GND with VRWM 5V max and ±30kV ESD rating. |
| 6 | I/O5 | passive | TVS-protected line 5 (one of five channels), clamping to GND with VRWM 5V max and ±30kV ESD rating. |
