CM1214A

• Single channel ESD protection for an AC signal up to +5V for 0.25W transmit power
• Connects two channels in series for signals up to +10V (1W transmit power)
• ±8kV ESD protection per IEC 61000-4-2 contact discharge
• Sub-1pF loading capacitance
• Minimal variation with voltage and temperature
• Each I/O pin can withstand over 1000 ESD strikes*
• SOT23-3 and MSOP-8 lead-free packages

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 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.

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 lead-free finishing.
