What is The USBLC6-2SC6?
The USBLC6-2SC6 is a STMicroelectronics 2-line, very low capacitance ESD protection diode array in a 6-pin SOT23 package, rated 5.25V standoff and 17V clamp for USB 2.0 and other high-speed data lines.
- Protects USB 2.0, Ethernet, SIM card, and video lines against surge and static discharge.
- About 3.5 pF line capacitance, low enough to sit directly on high-speed pairs without hurting signal integrity.
- 15 kV contact ESD rating, placed on the connector side of the data lines.
- One of the most designed-in protection parts across consumer, industrial, and communications boards.

Authorized ST Versus Clone Listings
Many of the cheapest USBLC6-2SC6 listings are not STMicroelectronics parts but look-alikes from houses such as SLKOR, UMW, and Goodwork, so the specific manufacturer dictates what buyers receive:
- STMicroelectronics branded: the original part, carried by every authorized distributor above.
- Non-ST manufacturers: SLKOR, UMW, Goodwork, Tech Public, FuxinSemi, and ElecSuper list their own USBLC6-2SC6 marked parts, often with different clamp and Ipp specs.
- Renamed order codes: listings such as TPUSBLC6-2SC6, USBLC6-2SC6-ES, and MSUSBLC6-2SC6 are house branded versions, not ST stock.
- What to verify: manufacturer name, datasheet clamp voltage, and distributor tier before you commit.
Next step: Filter USBLC6-2SC6 by STMicroelectronics to isolate authorized stock on Findchips.
