**TECH PUBLIC** · MOSFETs · SOT-23-6

TPE03K4S6 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 | IO1 | passive | ESD-protected I/O line (diode to GND), reverse working voltage 3.3 V max, clamping 15 V max at IPP = 20 A (8/20 µs), junction capacitance 200 pF max. |
| 2 | GND | power_in | Common ground (centre rail) of the TVS array, reference for the I/O protection diodes. |
