HDMIULC6-4F3
4-line IPAD™, ultra-large bandwidth ESD protection
Features
■ 4-line 15 kV ESD protection
■ Ultra low line capacitance (0.7 pF typ.)
■ Ultra-large bandwidth
– no influence on signal rise and fall times
– maximized number of signal harmonics
■ Flow-through layout with Type C HDMI™
connector
■ Low PCB space occupation - 1.76 mm²
footprint
■ Very low leakage current: 0.1 µA max.
■ 0.4 mm pitch WLCSP package to minimize
parasitic inductances
■ RoHS compliant
Complies with the standards:
■ IEC 61000-4-2 Level 4
– ± 15 kV (air discharge)
– ± 8 kV (contact discharge)
Application
■ Mobile phones
■ HDMI ports at 1.65 Gb/s and up to 3.2 Gb/s
■ USB 2.0 ports up to 480 Mb/s (Hi-Speed)
■ Video line protection

Description
The HDMIULC6-4F3 is a monolithic, application
specific discrete device dedicated to ESD
protection of the HDMI connection. It also offers
the same high level of protection for IEEE 1394a
and IEEE 1394b/c, USB 2.0, Ethernet links, and
video lines.
Its ultra high cutoff frequency (7 GHz) secures a
high level of signal integrity. The device topology
provides this integrity without compromising the
complete protection of ICs against the most
stringent ESD strikes.
