Product Description
The CM1206 family of transient voltage suppressor
arrays provides a very high level of protection for sensi-
tive electronic components that may be subjected to
ESD. The back-to-back Zener connections provide
ESD protection in cases where nodes with AC signals
are present.
These devices are designed and characterized to
safely dissipate ESD strikes at levels well beyond the
maximum requirements set forth in the IEC 61000-4-2
international standard. All I/Os are rated at +18kV
using the IEC 61000-4-2 contact discharge method.
Using the MIL-STD-883D (Method 3015) specification
for Human Body Model (HBM) ESD, all pins are pro-
tected for contact discharges to greater than +30kV.
The Chip Scale Package format of these devices
enable extremely small footprints that are necessary in
portable electronics such as cellular phones, PDAs,
internet appliances and PCs. The large solder bumps
allow for standard attachment to laminate boards with-
out the use of underfill.
The CM1206 incorporates OptiGuard™ coating which
results in improved reliability at assembly. The CM1206
is also available with optional lead-free finishing.
