Product Description
The PAC DN017 is a diode array designed to provide 18 channels of ESD protection for electronic components or
sub-systems. Each channel consists of a pair of diodes which steers the ESD current pulse either to the positive (V
P
) or
negative (V
N
) supply. In addition, there is an integral Zener diode between
V
P
and
V
N
to supress any voltage
disturbance due to these ESD pulses. The PAC DN017 will protect against ESD pulses up to 15 KV Human Body
Model, and 15KV contact discharge per International Standard IEC 61000-4-2.
This device is particularly well-suited to provide additional ESD protection for parallel printer ports. It exhibits low
loading capacitance for all signal lines.
