IP4220CZ6-L 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 data line I/O (Note 1: I/O pins are 1, 3, 4 and 6), 5V max reverse working voltage to ground, 0.8pF max to ground. |
| 2 | GND | power_in | Ground pin, the reference for all I/O pins (center zener diode anode in the schematic). |
| 3 | I/O2 | passive | TVS-protected data line I/O (Note 1: I/O pins are 1, 3, 4 and 6), 5V max reverse working voltage to ground, 0.8pF max to ground. |
| 4 | I/O3 | passive | TVS-protected data line I/O (Note 1: I/O pins are 1, 3, 4 and 6), 5V max reverse working voltage to ground, 0.8pF max to ground. |
| 5 | VCC | power_in | Upper rail of the diode array, tied to the cathode of the center zener diode in the schematic. The datasheet says the part protects one power line but does not name or describe this pin in text. |
| 6 | I/O4 | passive | TVS-protected data line I/O (Note 1: I/O pins are 1, 3, 4 and 6), 5V max reverse working voltage to ground, 0.8pF max to ground. |
