CM1214A Datasheet | California Micro Devices

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) ±8k V ESD protection per IEC 61000-4-2 contact discharge Sub-1p F 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 Product Description The CM1214A Pico Guard™ 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 es 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-1p F 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 e in 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. Electrical Schematics CH1 CH1 CH3 CH2 CM1214A-01SO CH2 CH4 CM 1214A-02MR - Standard test condition is IEC61000-4-2 level 4 test circuit with each pin subjected to ±8k V contact discharge for 1000 pulses. Discharges are timed at 1 second intervals and all 1000 strikes are pleted 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. © 2007 California Micro Devices Corp.
