AC Signal ESD Protector
CM1214A
Features
• 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 packages
• RoHS-compliant, 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.
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 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 RoHS-compliant, lead-free
finishing.

Performance Information
Typical Capacitance Characteristics vs. Voltage
CM1214A illustrates how the loading capacitance remains mainly flat across the voltage range from 0V to 5V,
the voltage between CH pins.
Figure 1. CM1214A Capacitance vs. Voltage
Typical Voltage Current (VI) Characteristics (low current)
CM1214A shows how the CM1214A experiences a symmetrical I/V curve, without any snapback or trigger
voltage. It gradually starts to turn on at about 6V and clamps about 7V.
