PESD3V3S4UD 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 | Protected uni-directional line 1 (steering-diode input), rated for 3.3V reverse working voltage and ±30kV IEC 61000-4-2 air/contact discharge. |
| 2 | GND | power_in | Ground reference for the TVS array, shown joined internally to pin 5 in the pin configuration drawing. |
| 3 | IO2 | passive | Protected uni-directional line 2 (steering-diode input), rated for 3.3V reverse working voltage and ±30kV IEC 61000-4-2 air/contact discharge. |
| 4 | IO3 | passive | Protected uni-directional line 3 (steering-diode input), rated for 3.3V reverse working voltage and ±30kV IEC 61000-4-2 air/contact discharge. |
| 5 | GND | power_in | Ground reference for the TVS array, shown joined internally to pin 2 in the pin configuration drawing. |
| 6 | IO4 | passive | Protected uni-directional line 4 (steering-diode input), rated for 3.3V reverse working voltage and ±30kV IEC 61000-4-2 air/contact discharge. |
