General Description
UESD6V8V4X are surge rated diode arrays designed to protect high speed data interfaces. This series
has been specifically designed to protect sensitive components which are connected to data and
transmission lines from over-voltage caused by ESD (electrostatic discharge).
The unique design incorporates surge rated, low capacitance steering diodes and a TVS diode in a
single package. During transient conditions, the steering diodes direct the transient to either the
positive side of the power supply line or to ground. The internal TVS diode prevents over-voltage on
the power line, protecting any downstream components.
The low capacitance array configuration allows the user to protect four high-speed data or
transmission lines. The low inductance construction minimizes voltage overshoot during high current
surges. This device is optimized for ESD protection of portable electronics. They may be used to meet
the ESD immunity requirements of IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact discharge).
