low capacitance steering diode array
Description
The ET108 is a low capacitance steering diode array designed to protect circuit applications with a bus voltage of less
than 25 volts from the effects of Electrostatic Discharge (ESD). This device is designed for the protection of four I/O
ports.
With a low input capacitance per line of less than 6pF, pulse two diode pairs for each line, the ET108 provides both
positive and negative transient protection. This device meets all the applicable voltage immunity standards, including
IEC 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (Surge).
