Product Description
The CM1214A PicoGuard® ESD protector is used to
protect bipolar signal lines against electrostatic
discharge (ESD). The CM1214A allows operation in
high-speed environments with signals levels up to
±5V.
The CM1214A comes in two versions:
The low sub-1pF loading capacitance makes the
CM1214A-01SO ideal for protecting high-speed
interfaces including RF switches and amplifiers.
The CM1214A-02MR is ideal for dual high-speed
signal pairs used in Gigabit Ethernet, ADSL, etc. The
CM1214A-02MR can also be used for higher transmit
voltage applications by connecting the two channels
in series.
Both devices come in RoHS-compliant, lead-free
finishing.
1- and 2-Channel PicoGuard®
The CM1214A-01SO is a single channel ESD
protector and is available in a 3-lead SOT23-3
package.
The CM1214A-02MR is a dual channel ESD
protector and is available in an 8-lead MSOP-8
package.
