DVIULC6-4SC6
Ultra low capacitance ESD protection
Main applications

DVI ports up to 1.65 Gb/s HDMI ports up to 1.65 Gb/s IEEE 1394a and IEEE 1394b ports up to 1.6 Gb/s USB2.0 ports up to 480 Mb/s (high speed), backwards compatible with USB1.1 low and full speed Ethernet port: 10/100/1000 Mb/s SIM card protection Video line protection

SOT23-6L (JEDEC MO178AB)

Complies with these standards:

IEC61000-4-2 level 4 15 kV (air discharge) 8 kV (contact discharge)

Description
The DVIULC6-4SC6 is a monolithic, application specific discrete device dedicated to ESD protection of high speed interfaces, such as DVI, HDMI, IEEE 1394a and IEEE 1394b, USB2.0, Ethernet links and video lines. Its ultra low line capacitance secures a high level of signal integrity without compromising in protecting sensitive chips against the most stringent characterized ESD strikes.

Benefits

ESD standards compliance guaranteed at device level, hence greater immunity at system level ESD protection of VBUS when applicable. Allows ESD current flowing to Ground when ESD event occurs on data line Optimized rise and fall times for maximum data integrity Consistent D+ / D- signal balance: Best capacitance matching tolerance I/O to GND = 0.015 pF for ultra low inter pair skew Best capacitance matching tolerance I/O to I/O = 0.007 pF for ultra low intra pair skew Matching high bit rate DVI, HDMI, and IEEE 1394 requirements Low PCB space consuming, 9mm maximum foot print Low leakage current for longer operation of battery powered devices Higher reliability offered by monolithic integration

Features

4 line ESD protection Protects VBUS when applicable Ultra low capacitance: 0.6 pF at F = 825 MHz Fast response time SOT23-6L package RoHS compliant
