APPLICATION NOTE

The VBUS05M2-HT5 is a two-line ESD protection device with a bidirectional and symmetrical (BiSy) breakdown and clamping

performance made for application with a voltage working range up to ± 5.5 V. The high ESD immunity and a very low

capacitance makes it usable for high frequency applications like USB2.0, USB3.0, or HDMI.

With the VBUS05M2-HT5 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 above

the 5.5 V working range.

SCHEMATIC DIAGRAM

Fig. A

The simplified schematic diagram in Fig. A shows three identical Z-diodes with the cathode on pin 1, 2, or 3 and common

anodes. In reality each Z-diode consist of one Z-diode for the adjustment of the breakdown voltage, and two low capacitance
