General Description
UM5204EEXF 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).
