描述 Description

AZ1575-04S is a high-performance design which

includes surge rated diode arrays to protect

high-speed data interfaces. The AZ1575-04S 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.

AZ1575-04S 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.

AZ1575-04S may be used to meet the ESD

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

(?15kV air, ?8kV contact discharge).
