In cases of using TVS diodes showing a higher capacitance, very extreme modifications on the PCB layout are necessa-
ry in order to compensate the diode capacitance and be able to meet the TDR specification window of 100Ω ±15% and
the more stringent value of +-10% for the HDMI load.
Therefore ultralow capacitance ESD protection devices like ESD5V3U4U-HDMI with a capacitance remaining at or be-
low 0.4pF (line to ground) over a frequency range from 1MHz to beyond 3GHz are mandatory to keep signal’s integrity
at an optimum without complex compensation PCB structures.
Cleanest PCB layout for easy design
ESD5V3U4U-HDMI is a very eective solution supporting quicker time to market and reduces purchasing complexity
as each array device can be easily implemented to replace 4 discrete components. ESD5V3U4U-HDMI can save up to
50% board space in comparison with e.g. ceramic protection devices in case size 0402 as one array device can protect
four high speed data lines at the same time.
In applications like HDMI 1.3 or DisplayPort, the pin spacing of the connectors is 0.5mm, just the same as the pitch
spacing of ESD5V3U4U-HDMI in TSLP-9 package. It means this array device can be placed on top of two dierential
microstrip line pairs, avoiding multiple stubs and bends in the PCB traces that would cause reflections and signal at-
tenuation. For further information about this as well as other members from the ultralow capacitance TVS diode series
