CM1214

PRELIMINARY www.DataSheet4U.com CM1214 1 and 2 Channel PicoGuardTM AC Signal ESD Protector Features Single channel ESD protection for an AC signal up to ±5V for 0.25W transmit power Connect 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 Can withstand over 1000 ESD strikes at 8kV DFN-3, SOT23-3 and MSOP-8 package options Lead-free versions available Product Description The CM1214 PicoGuardTM ESD protector is used to protect bipolar signal lines against electrostatic discharge (ESD). The CM1214 allows operation in highspeed environments with signals levels up to +5V. The low sub-1pF loading capacitance makes the CM121401DF/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 i...
