Frequently Asked Questions
How does the USBLC6-4SC6Y's 0.5 pF capacitance affect USB 2.0 high-speed signal integrity?
At 0.5 pF typical line capacitance per channel, the USBLC6-4SC6Y adds negligible loading to USB 2.0 differential pairs operating at 480 Mbps, ensuring eye-diagram compliance and minimal insertion loss. This is significantly lower than general-purpose TVS diodes, which often exceed 5 pF and can distort high-speed signals.
What ESD protection level does the USBLC6-4SC6Y provide and under which standard is it rated?
The USBLC6-4SC6Y provides ±8 kV ESD protection per IEC 61000-4-2 contact discharge and ±15 kV air discharge, clamping transients to a maximum of 17 V. This level of protection covers the full range of human body model discharge scenarios encountered in consumer and industrial USB applications.
Can USBLC6-4SC6Y protect both the D+ and D- lines of a single USB port simultaneously?
Yes. The USBLC6-4SC6Y integrates 4 unidirectional protection channels in a SOT-23-6 package, so it can protect all 4 signal lines of two USB ports or both D+ and D- lines of a single USB 2.0 port plus two additional signals such as VBUS or CC lines in a single device.
