| ULTRA LOW CAPACITANCE ESD PROTECTION ARRAY FOR HIGH SPEED I/O PORT
DESCRIPTION
The UTC UESD5V0U4U01 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 UESD5V0U4U01 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 UESD5V0U4U01 may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4 (±15kV air,
±8kV contact discharge)
