CM1213

www.DataSheet4U.com CM1213 1, 2, 4, 6 and 8-Channel Low Capacitance ESD Protection Arrays Features 1, 2, 4, 6 and 8 channels of ESD protection Provides ESD protection to IEC61000-4-2 Level 4 - 8kV contact discharge - 15kV air discharge Low channel input capacitance of 1.0pF typical Minimal capacitance change with temperature and voltage Channel input capacitance matching of 0.02pF typical is ideal for differential signals Mutual capacitance between signal pin and adjacent signal pin - 0.11pF typical Zener diode protects supply rail and eliminates the need for external by-pass capacitors Each I/O pin can withstand over 1000 ESD strikes Available in SOT, SOIC and MSOP packages Lead-free version available Product Description The CM1213 family of diode arrays has been designed to provide ESD protection for electronic components or sub-systems requiring minimal capacitive loading. These devices are ideal for protecting systems with high data and clock rates or for circuits requiring low capacitive loading. Each ESD channel consists of a pair of diodes in series which steer the positive or negative ESD current pulse to either the positive (VP) or negative (VN) supply rail. A Zener diode is embedded between VP and VN, offering two advantages. First, it protects the VCC rail against ESD strikes, and second, it eliminates the need for a bypass capacitor that would otherwise be needed for absorbing positive ESD strikes to ground. The CM1213 will protect against E...
