TRANSIENT PROTECTION DIODES

DESCRIPTION

The UTC UESD5V0U4U03 is a design which includes ESD

rated diode arrays to protect high speed data interfaces. The

AZ1045-04F has been

specifically designed to protect sensitive components which

are connected to data and transmission lines from over-voltage

caused by Electrostatic Discharging (ESD).

The UTC UESD5V0U4U03 is a unique design which includes

ESD rated, ultra 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 internal ESD line or to ground

line. The internal unique design of clamping cell prevents

over-voltage on the internal ESD line and on the I/O line, which is

protecting any downstream components.

The UTC UESD5V0U4U03 may be used to meet the ESD

immunity requirements of IEC 61000-4-2, Level 4 (±20kV air,

±20kV contact discharge).
