The USBLC6-2SC6 is a monolithic application-specific device dedicated to ESD protection of high-speed interfaces, such as USB 2.0, Ethernet links, and video lines. It is a very low capacitance ESD protection diode with a maximum clamping voltage of 17 V. It has a maximum ESD protection device voltage of 15 kV (air gap) and 15 kV (contact discharge).

The USBLC6-2SC6 is ideal for protecting sensitive equipment against electrostatic discharges (ESDs), which are sudden bursts of electrical current that can damage electronic components. ESDs can be caused by everyday activities such as touching a doorknob or walking across a carpet.

The USBLC6-2SC6 is packaged in a compact SOT-23-6 package, making it ideal for use in space-constrained applications. It is also AECQ-101 qualified for automotive applications.

How to use the USBLC6-2SC6

The USBLC6-2SC6 should be connected in parallel with the high-speed interface lines that need to be protected. It is important to connect the USBLC6-2SC6 as close as possible to the I/O pins of the protected device. This will help to minimize the parasitic inductance and resistance of the traces, which can degrade the ESD protection performance.

The following is a typical application circuit for the USBLC6-2SC6:

Design considerations

When using the USBLC6-2SC6, it is important to consider the following:

• The USBLC6-2SC6 has a maximum clamping voltage of 17 V. This means that it will clamp any voltage that exceeds 17 V to 17 V. This can be important for protecting sensitive devices that are not able to withstand voltages higher than 17 V.
• The USBLC6-2SC6 has a maximum ESD protection device voltage of 15 kV (air gap) and 15 kV (contact discharge). This means that it will protect the protected device from ESD strikes up to 15 kV. However, it is important to note that the ESD protection performance of the USBLC6-2SC6 can be affected by the layout of the PCB. It is important to follow the layout recommendations in the USBLC6-2SC6 datasheet to ensure that the USBLC6-2SC6 provides the best possible ESD protection.

Conclusion

The USBLC6-2SC6 is a very low capacitance ESD protection diode that is ideal for protecting high-speed interfaces from ESD strikes. It is AECQ-101 qualified for automotive applications and is packaged in a compact SOT-23-6 package.
