ET721
Only One Name Means ProTek’Tion™
ultra low capacitance steering diode array
Description
The ET721 is a low capacitance and low leakage steering diode array capable of protecting up to six (6) high speed
data lines. 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. An extremely low leakage current makes the ET721 suitable for
battery powered devices.
The ET721 is available in a SO-8 package. This device meets all the applicable voltage immunity standards, including
IEC 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (Surge).
