PSRDA70-4

ultRA low cAPAcitAnce SteeRing DioDe ARRAy

DeScRiPtion

The PSRDA70-4 is an ultra low capacitance steering diode array designed to protect circuit applications from the ef-

fects 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).
