With the new ESD5V3U4U-HDMI TVS diode array, Infineon combines ESD protection with high-speed signal integrity and a straightforward PCB layout. The product targets digital televisions, DVD / Blu-ray players, recorders, game consoles, digital set-top boxes, LCD monitors and mobile communication equipment.
Applications include HDMI1.3, DisplayPort, USB 3.0, FireWire and MicroSD interface. The device is qualified to ensure ESD strikes of up to 20 kV (contact and air discharge), exceeding the standard IEC61000-4-2 level 4.
One of the most critical tests in the HDMI certification is the TDR (time domain reflectometry) characterisation of the HDMI sink eg, for an HD-TV. Even a small amount of added capacitance on an HDMI port precipitates a drop in the impedance of the differential pair, which can lead to heavily attenuated signals and consequently to certification compliance issues. For this reason, low-capacitance ESD protection devices like the ESD5V3U4U-HDMI – with a capacitance remaining at or below 0,4 pF (line to ground) over a frequency range from 1 MHz to beyond 3 GHz – are essential to keep signal integrity at an optimum without complex compensating PCB structures.
The array can save up to 50% board space in comparison with eg, 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 0,5 mm, identical to the pitch spacing of the ESD5V3U4UHDMI in the TSLP-9 package. This means that the device can be placed on top of two differential microstrip line pairs, avoiding multiple stubs and bends in the PCB traces that would cause reflections and signal attenuation.
