DESCRIPTION

The UTC UESD5V0U4U02 is a high performance and low

cost design which includes surge rated diode arrays to protect

high speed data interfaces. The UTC UESD5V0U4U02 family has

been specifically designed to protect sensitive components, which

are connected to data and transmission lines, from over-voltage

caused by Electrostatic Discharging (ESD), Electrical Fast

Transients (EFT), and Lightning.

The UTC UESD5V0U4U02 is a unique design which includes

surge rated, low capacitance steering diodes and a unique design

of clamping cell which is an equivalent TVS diode in a single

package. During transient conditions, the steering diodes direct

the transient to either the power supply line or to the ground line.

The internal unique design of clamping cell prevents over-voltage

on the power line, protecting any downstream components.

The UTC UESD5V0U4U02 may be used to meet the ESD

immunity requirements of IEC 61000-4-2, Level 4 (± 15kV air,

±8kV contact discharge).

FEATURES
