Overview

PSRDA70-4

The PSRDA70-4 is an ultra low capacitance steering diode array designed to protect circuit applications from the effects of Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT). Its ultra low capacitance allows maintenance of signal integrity for high-speed data lines while protecting the circuit ICs from the damage of severe transients. This device is designed for the protection of four lines. Packaged in an SO-8 configuration, this device meets all the applicable voltage immunity standards, including IEC 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (Surge).
