DESCRIPTION
The EiMDXXC8 series of monolithic
transient voltage suppressors are designed
for applications where voltage transients,
caused by electrostatic discharge (ESD) and
other induced voltage surges, can
permanently damage voltage sensitive
components. These monolithic TVS diodes
are characterized by their high surge
capability, extremely fast response time and
low on-resistance.
Schematic:
The EiMDXXC8 is designed to provide
transient suppression on multiple data lines
and I/O ports. The low profile SO-14 design
allows the user to protect up to eight data
and I/O lines with one package. The
bidirectional device and may be used on
lines where the normal operating voltage is
above and below ground (i.e. +12V to -12V).
The EiMDXXC8 TVS diode network will
meet the surge requirements of IEC 1000-4-
2, Level 4, "Human Body Model" for air and
contact discharge.
