UM5202EEDF
Dual Channel Low Capacitance ESD Protection Array
UM5202EEDF SOT143
General Description
UM5202EEDF is 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 two 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).
