ESD Protection Component Inquiry

what is that component used for?

Thought for 2 mins

If you mean USBLC6-2SC6Y, it’s an ultra‑low‑capacitance, bidirectional TVS diode array used to protect high‑speed data interfaces (commonly USB D+ and D−, and VBUS) from ESD and surge events by clamping spikes to ground.

Practical notes

Place it as close to the connector as possible with a short, low‑impedance path to ground.
Based on Flux knowledge base guidance: for USB data‑line ESD protection use bidirectional TVS and keep capacitance below 1 pF per line, to preserve signal integrity.

If you were referring to a different component, tell me its designator and I’ll explain that one.
