Description

AZ1045-04QU is a design which includes surge

rated diode arrays to protect high speed data

interfaces. The AZ1045-04QU has been

specifically designed to protect sensitive

components which are connected to data and

transmission lines from over-voltage caused by

Electrostatic Discharging (ESD).

AZ1045-04QU is a unique design which includes

surge 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

power supply line or to ground line. The internal

unique design of clamping cell prevents

over-voltage on the power line, protecting any

downstream components. Besides, there is a

back-drive protection design in AZ1045-04QU for

power-down mode operation.

AZ1045-04QU may be used to meet the ESD

immunity requirements of IEC 61000-4-2, Level 4

(±15kV air, ±8kV contact discharge).
