Product Description
The CM1214
PicoGuard
TM
ESD protector is used to
protect bipolar signal lines against electrostatic dis-
charge (ESD). The CM1214 allows operation in high-
speed environments with signals levels up to +5V. The
low sub-1pF loading capacitance makes the CM1214-
01DF/DE and CM1214-01ST/SO ideal for protecting
high-speed interfaces including RF switches and
amplifiers. The CM1214-02MS/MR is ideal for dual
high-speed signal pairs used in Gigabit Ethernet,
ADSL, etc. The CM1214-02MS/MR can also be used
for higher transmit voltage applications by connecting
the two channels in series.
The CM1214-01DF/DE and the CM1214-01ST/SO are
single channel ESD protectors available in a 3-lead
DFN-3 and SOT23-3 packages respectively. The
CM1214-01DF/DE is housed in a very small form fac-
tor DFN package that provides up to 20% and 32%
board space savings when it is used in place of SC70
and SOT23 packages. The CM1214-02MS/MR is a
dual channel ESD protector and is available in an 8-
lead MSOP-8 package. All three devices are available
with optional lead-free finishing.
Applications
RF switch and amplifier protection
RF modules and RF IC protection
Wireless handsets and WLAN
High-speed AC signals for Gbit Ethernet, etc.
