The PSRDA70-4 is an ultra low capacitance steering diode array designed to protect circuit applicaons from the ef-
fects of Electrostac Discharge (ESD) and Electrical Fast Transients (EFT). Its ultra low capacitance allows maintenance
of signal integrity for high-speed data lines while protecng the circuit ICs from the damage of severe transients. This
device is designed for the protecon of four lines.
Packaged in an SO-8 conguraon, this device meets all the applicable voltage immunity standards, including IEC
61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (Surge).
Compable with IEC 61000-4-2 (ESD): Air - 15kV, Contact - 8kV
Compable with IEC 61000-4-4 (EFT): 40A - 5/50ns
Compable with IEC 61000-4-5 (Surge): 24A, 8/20µs - Level 2(Line-
Gnd) & Level 3(Line-Line)
Provides 4 Lines/Ports of Protecon
Low Leakage Current
Ultra Low Capacitance: 6pF Typical
