format product datasheet

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.

FEATURES

APPLICATIONS
  • 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
  • RF switch and amplifier protection
  • RF modules and RF IC protection
  • Wireless handsets and WLAN
  • High-speed AC signals for Gbit Ethernet, etc.*Standard test condition is IEC61000-4-2 level 4 test circuit with each pin subjected to ±8kV contact discharge for 1000 pulses. Discharges are timed at 1 second intervals and all 1000 strikes are completed in one continuous test run. The part is then subjected to standard production test to verify that all of the tested parameters are within spec after the 1000 strikes.
