APPLICATION NOTE
The VBUS052CD-FAH is a two-line ESD-protection device with the characteristic of a Z-diode with a high ESD immunity and
a very low capacitance which makes it usable for high frequency applications like USB2.0 or HDMI.
With the VBUS052CD-FAH two high speed data lines can be protected against transient voltage signals like ESD (Electro Static
Discharge). Connected to the data line (pin 1 and pin 2) and to ground (pin 3) negative transients will be clamped close below
the ground level while positive transients will be clamped close above the 5 V working range. The clamping behaviour of the
VBUS052CD-FAH is bidirectional but asymmetrical (BiAs) and so it offers the best protection for applications running up to 5 V.
Pin configuration:
• Pin 3, 4 and 7 are internally shorted and have to be connected to ground
• Pin 1 and 2 are the inputs for the data lines D+ and D• Pin 5 and 6 are not connected internally

FLOW THROUGH DESIGN
Modern digital transmission lines can be clocked up to 480 Mbit/s (USB2.0) or 1.65 Gbit/s (HDMI).
At such high data rates the transmission lines like cables or the line traces on the PCBs have to be very homogeneous regarding
their surge impedance. This requires well defined trace dimensions as trace width and distance which have to be calculated
depending on the requested surge impedance (e.g. 50 Ω) and the PCB material and layer dimensions. Any device connected
to the data lines - like ESD-protection devices - have to be connected with minimal changes in these trace dimensions and
distances.
With the package in the so called “Flow Through Design” this is possible. The lines are running straight along the PCB while the
VBUS052CD-FAH is placed on top without any vias or loops.
