Overview of USBLC6

For sensitive semiconductor components and common electronic products, protection from   ESD, EFT and lightning is necessary, but incorporating diode protection can introduce capacitance which reduces the bandwidth of data transmission lines. The USBLC6 is an integrated ESD protection diode array that can incorporates multiple diodes, can protect two data lines and is also capable of protecting the bus voltage of that transmission line. USBLC6 has a low capacitance of 2.5pF and low leakage current of 150nA.

USBLC6 diode array has four surge rated, low capacitance steering diode and a Zener diode in a single package to protect each I/O pin against ESD and high surge events. Internal circuit diagram for USBLC6 is shown below.

When the transient condition occurs, steering diodes direct the transient to ground or positive side of power supply.
