• ±8kV ESD protection per IEC 61000-4-2 contact discharge
• Sub-1pF loading capacitance
• Minimal variation with voltage and temperature
• Can withstand over 1000 ESD strikes at 8kV
• DFN-3, SOT23-3 or MSOP-8 package
• Lead-free versions available

The CM1214 PicoGuard™ ESD protector is used to protect bipolar signal lines against electrostatic discharge (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 factor 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.
