IP4220CZ6-L

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-23-6

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.
