DVIULC6-4SC6Y
Automotive ultralow capacitance ESD protection
Datasheet production data
Features
■ 4-line ESD protection (IEC 61000-4-2)
■ Protects V
BUS
when applicable
■ Ultralow capacitance: 0.6 pF at F = 825 MHz
■ Fast response time compared with varistors
■ RoHS compliant
■ AEC-Q101 qualified
Benefits
■ ESD protection of V
BUS
■
Optimized rise and fall times for maximum data
integrity
■ Consistent D+ / D- signal balance:
– Optimum capacitance matching tolerance
for ultralow intra pair skew:
I/O to ground = 0.015 pF,
I/O to I/O = 0.007 pF
– Matching high bit rate DVI, HDMI, and
IDB 1394 bus requirements
■ Low PCB space occupation: 9 mm
2
■
Higher reliability offered by monolithic
integration
Complies with these standards

Description
The DVIULC6-4SC6Y is a monolithic, application
specific discrete device dedicated to ESD
protection of high speed interfaces, such as DVI,
HDMI, IDB 1394 bus, USB2.0, Ethernet links and
video lines.
Its ultralow line capacitance secures a high level
of signal integrity without compromise in
protecting sensitive chips against the most
stringently characterized ESD strikes.
